Compliant With Vibrance

Fusing Culture, Community & Accessible Design

Context — A Synthesis Of Art, Culture & Local Flavors

A collaboration between DoorDash and Berlin-based design studio Studio Yukiko, Secret Menu is a digital and print magazine that amplifies the voices of restaurant owners, spotlighting the contributions they make to their local communities and the industry as a whole.

Aesthetically, Secret Menu is edgy on purpose, provocative: an effort to emulate the mosaic of life stories and cultures it celebrates. The art in its pages can be photorealistic, retro, collage or surrealist. The color scheme for one article may be triadic; for another, split-complementary or monochromatic. Typography might be modern, script or condensed.

Content is also mosaic: a blend of biographies, interviews, photo essays and feature articles that explain everything from how a small, undecorated food stand, rebuilt after Hurricane Dorian, used solar power to become one of the most successful local shops; to how the impact of climate change led one family to farm their own pineapples and currants—vital ingredients for the pastelitos they sell from their mobile bakery.

Secret Menu centers each issue on a different American city. Its first iteration lived in Los Angeles, exploring its iconic dishes, high-end dining and history with farm-to-table. Edition number two moved to Miami: touring its food trucks and ventanitas and impossibly fresh seafood, as well as the “almighty hustle” of its merchants who are inspired every day by the cuisine of South America, Latin America and the Caribbean.

Challenge — Creative Freedom Meets Digital Constraints

The Medium Designs The Message

As the marketing automation team, we led the development of a campaign that announced the launch of this most recent Secret Menu edition to digital subscribers. Our objective was twofold. Of course, we wanted to unlock favorable channel metrics, especially with regard to read rate and click-through rate: indicators of how well content had been researched, timed, written, designed and targeted.

Secondly, though, and in this case, no less essentially, we hoped to create an email series that lived up to the powerful Secret Menu aesthetic that DoorDash and Studio Yukiko had worked so hard to cultivate.

But there was a problem. The unique patchwork of colors, typographies and art styles that leapt from the magazine page did not translate well to email: a medium where less is often more, where white space is treasured, and where classic visual hierarchies are often best for giving users an easy and intuitive way to process information.

Secret Menu, in other words, could afford to be designed boldly and wildly—could afford, as Lupton and Xia write in Extra Bold, to “protest” and “resist” the “deeply embedded norms” of design, which historically lean toward symmetry and ‘staticness’ and even predictability, via the use of “diagonal lines, mismatched fonts and montaged photos.”

Its digital campaign, however, could not afford this. Helvetica, with its iconic versatility, would be the font. Images would be simple and homogenous: purchased from Shutterstock, not painted or patterned in Photoshop as they’d been for web properties. And colors, far from the Art Deco pastels and Ocean Drive neons of the print booklet, would hew to our classic brand palette, which centered on DoorDash Red (#fb321e).

As we explained to stakeholders, this straight-laced approach was necessary for email for two reasons:

  1. The digital campaign would be rooted in email content—which people can unsubscribe from and report as spam, damaging the sender reputation of DoorDash. Further, these emails would be following in the branded footsteps of the millions of emails that preceded them. Subscribers have expectations. And meeting those expectations—being “on-brand”—is important. It contributes to our brand recognition, the clarity of our message and even the trust consumers build with us across touchpoints.

  2. The Secret Menu magazine, only the second of its kind at DoorDash, was comparatively unweighed by design precedent. And magazines have more space than emails, are more trusted, and in print are more stable upon delivery, unaffected by inboxes that can block images or devices in dark mode. As such, it is safer to experiment in magazines. If someone doesn’t like what they see, it is much harder for them to unsubscribe and there is no account manager or policing platform to report it to.

Accessibility

Our team was also concerned about accessibility. While stakeholders understandably were moved by the prospect of delivering emails as beautiful as the booklet, we had to step in and speak up for best practice—which, in this case, meant ensuring our content was legible for as many contacts as possible and adhered to WCAG 2 standards.

Some color combinations—though eye-catching in pull quotes, image shadows, background colorways and other accents—did not achieve the contrast ratio required for information to be considered accessible. Accessibility is about more than color combination! In our use case, though, it was the most pressing consideration to ensure text was readable.

The Design team had used greens, yellow, blues and pinks to evoke the skylines and seascapes of the Magic City. However, we in marketing must always remember our audience. Eight percent of men and 0.5% of women in the U.S. (where this campaign was focused) are affected by some form of color blindness, which would be about 20 million email users.¹

All of our palettes were reanalyzed.

On the pastel front, for example, Grape Green (#a1e5a1) and Sunset (#ffd699) and Peach Flesh (#ffc3a0)—evocative of the fruit festivals and tropical trees of Miami—had to be axed. The same was true for Sky Blue (#a2d6f9) and Light Pink (#ffb6c1) and Mauve (#d5aaff): While an homage to watercolor sunsets, these hues did not pass WCAG quality control.

A nod to South Beach and boat shows, the neon palette fared no better. Safety Orange (#ff5e00) and Neon Pink (#f535aa) when paired were unreadable for users with a visual impairment, as were Cyan (#00d4ff) and Psychedelic Purple (#d300ff).

Even the initial solution proposed by the Secret Menu team, backgrounds of DoorDash Red (#fb321e) with headers and quotes of Blush Pink (#f1acc9), could not be used, as they failed contrast checks for normal-size text, large text, graphical objects and user interface components.

Unexpectedly, this pulled a new thread, one much bigger than any individual campaign: the fact that DoorDash Red, a frequent background color in web, social and email marketing, did not meet accessibility standards when paired, simply, with the color white. This combination, which at the time was branded everywhere, is only accessible in specific contexts and is not accessible at all for normal-sized text.

Resolution — New Palettes

Though we were not able to use exactly the same palettes the magazine used, in the end we and the Design team were able to agree on several color combinations that simultaneously paid tribute to Miami, complemented the aesthetic of the magazine and provided an accessible experience to all subscribers.

For example, the blues and pinks made famous by the Art Deco architecture of the Magic City could be combined accessibly if we were to launch with Lavender Pink (#ffc0cb) and Teal Blue (#008080).

Greens and yellows could find a home in the campaign with Sunflower Yellow (#ffd700) and Fern Green (#4f7942), symbolic of the non-native but ubiquitous Miami pineapple.

Even a few surprising partnerships, like pink on pink and blue on blue, were unearthed after careful and collaborative tinkering with designers. Bubblegum (#ffc3d0) and Raspberry (#e30b5d) were an accessible shock, as were Alice (#f0f8ff) and Sapphire (#0f52ba).

Notably, though, all of these combinations (minus Alice on Sapphire) were only accessible for large text. And even then, as confirmable at their permalinks, contrast ratios were only passably accessible: AA but not AAA.

For the body text in our messages—where core storytelling took place that reminded subscribers what Secret Menu is, why it’s important and who it celebrates, and also where we linked out to its gorgeous microsite—we knew we had to aim much higher, and we deliberately pursued an AAA score, the gold standard in accessibility.

Specifics — Luminance

We leveraged the AA combinations to create AAA combinations to go to market with. Our favorite inspiration was the duo of pink and blue because it evoked the hues of Miami Vice, the influential 1980s television show known for its stylish visuals and vibrant atmosphere, and whose palette is still visible everywhere from sneaker culture to Miami Heat basketball jerseys.

Lavender Pink (#ffc0cb) and Sapphire (#0f52ba) were our starting point. With a contrast ratio of 4.65 to 1, these two colors were not AAA for normal-sized text. But we understood that we could increase this ratio to 7 to 1—where it needed to be for AAA—by decreasing luminance, the measure of the brightness of a color.

An objective attribute that corresponds to the intensity of light emitted or reflected by a surface, luminance in digital color is often calculated from the RGB (Red, Green, Blue) values of a color. Here is the formula for calculating relative luminance (Y) from RGB values:

Y = 0.299 × R + 0.587 × G + 0.114 × B

The resultant Y is a weighted sum (expressed in “nits”) that represents the perceived brightness of a color. Typically its value will range from 0 to 255 in the RBG color model, with 0 being the darkest (black) and 255 being the brightest (white). This means that decreasing luminance, driving its value closer to zero, also darkens it, driving it closer to black.

The RGB values for Sapphire (#0f52ba) are 15 for Red, 82 for Green and 186 for Blue. We could therefore calculate its luminance:

Y = 0.299 × R + 0.587 × G + 0.114 × B

Y = 0.299 × 15 + 0.587 × 82 + 0.114 × 186

Y = 4.485 + 48.034 + 21.204

Y ≈ 73.723

Confirming the luminance of Sapphire (about 73.7 nits), we dove into creating a new similar color with reduced luminance: a darker blue that, when paired with Lavender Pink, would yield a higher contrast ratio and consequently a better accessibility score.

After experimenting with a few options (some shades were so dark they felt black in Figma mockups, and some shades were so light they still were not max-compliant), we landed on the optimal solution: a barely bluer take on Catalina (#0c3a7f). With 30.77% less luminance than Sapphire, this color was dark enough to unlock AAA compliance with WCAG but still blue enough to pay homage to Miami’s scene and culture colors.

The resultant pairing with Lavender Pink achieved a 7.08 to 1 contrast ratio, meeting the minimum requirement of 7 to 1 for an AAA rating.

Results — More Clicks, More Eyeballs & More Future Subscribers

Our dedication to crafting emails both beautiful and accessible led to remarkable results, surpassing benchmarks for three key performance indicators.

Click-to-open rate exceeded our internal benchmark for mid-funnel marketing by 132%. Read rate, which measures the proportion of recipients who read an entire marketing message from top to bottom, outperformed the industry-agnostic standard by 74%.² And unsubscribe rate, which indicates the percentage of recipients who opted out of similar outreach, exceeded best practice by 29%.³

These results prove the strength of our approach to design for this campaign.

In finding the compromise between accessible coloration and bold aesthetics, we produced content that enabled great engagement for the emergent Secret Menu brand.

We created marketing that was not only visually appealing, evocative of our legendary host city and at times even surprisingly bold—but that was also mindful of the expectations of our audience, the context and guidelines of email as a digital medium, and the need on our part to be as compliant and inclusive as possible in order to connect with the largest number of subscribers.
