Murals of the World: the look, the colors, and tasteful sponsors

The question

muralsoftheworld.com is a free public record of about 17,700 murals, one page per wall, with artist credit and a permission request form. The look is bold sign-painter blocks of color: signal yellow, hot pink, sky blue, kelly green, paper and ink. Each wall and artist page takes one color, and the M logo now changes color by page. Yellow dominates the site; green and blue rarely get a big header block, so the palette we chose for the map doesn't come through across the site. Is this the right visual approach, what elements would you add, and how should the colors be used more evenly?…

The council's call, where it split, and what would change it.

The answer

The council's answer

Keep the flat sign-painter look (your option A) and fix how colors are assigned. Count the live header colors first, then give each wall and artist page its color by record ID split four ways, so yellow, pink, blue and green each land near 25% of headers. Add a large artist credit and clearer record details instead of drips or textures, because the wall photo is the texture and artist trust depends on seeing their name right and first. Put no sponsor on the site this month. Later, a sponsor gets one plain text line on a city or tour page only, never a "colors by [brand]" layer.

Where the council agreed and split

1Unanimous

No drips, spray marks, grain or paint textures. Seats saw them as a long-used festival and streetwear graphic (from memory), and passing a contrast check makes a page readable but does not earn artist trust.

Assign colors by record ID, not by city. Big cities would turn whole regions one color, and city colors would need text labels anyway (https://www.w3.org/WAI/WCAG22/Understanding/use-of-color.html). After switching, check the pages people open most (home, city, wall) so the balance holds where visitors look.

Use sign-painter lettering for headings and the credit line. Keep plain type for body text and forms, and keep forms on paper and ink.

4Unanimous

Keep brands off artist pages, wall pages, claim flows, permission forms, the map and the M, and drop "colors by [brand]." A brand next to a wall implies the artist used or endorses that paint. FTC guidance says a logo alone is generally not enough disclosure (https://www.ftc.gov/business-guidance/resources/native-advertising-guide-businesses), so the credit has to be words that match the deal, for example: "Documentation supported by [brand]. They have no say in which walls we list."

Pitch a defined, paid documentation project for one city, not paint donations alone, because donated materials don't pay for running the site. Benjamin Moore's donation form excludes individuals and non-charities (https://www.benjaminmoore.com/en-us/donation-request), so approach it commercially. Sherwin-Williams and Benjamin Moore fit flat brush paint. Montana sells spray cans (from memory), so ask it only for general support through its help-center chat (https://helpcenter.montana-cans.com/en/articles/32338-sponsoring-inquiry).

Caught by one seat

What would change the answer

Next steps

  1. Run a 30-day test. This week, count header colors on 100 live pages, switch to the record-ID rule, and ship the credit line. Across the invites at 10 a day (the brief), track claim rate and reply themes. Keep the design if claims hold at or above 20% (unverified benchmark). If replies mention missing photos, wrong credits or "who made this page," move effort from color to record details.
  2. Set the text color for each of the four header colors so normal text passes 4.5:1 and large text passes 3:1 (https://www.w3.org/WAI/WCAG22/Understanding/contrast-minimum.html). It worked when every pair passes in a contrast checker.
  3. Label photo-less pages "No photo of this wall yet. Have one? Send it and we'll credit you by name." Show Street View only as embeds, since Google bans screenshots (https://about.google/intl/en-GB_ALL/brand-resource-center/products-and-services/geo-guidelines/). It worked when no wall page holds a Street View screenshot.
  4. By day 30, write your sponsor terms (no editorial control, no paid ranking, no artist contact sharing) and send a one-city proposal to Sherwin-Williams and Benjamin Moore. It worked when either replies to discuss cash on those terms.

Method

Research: before any seat answered, a researcher with web search gathered the outside facts the decision turns on, with links, and every seat read them. Round 1: each seat answered alone. Round 2: each seat read every round-one answer without knowing who wrote it, ruled on the disagreements and revised. Round 3: the Chief of Staff wrote this report from both rounds.
