Automated Coolors Palette Contrast Audit
Every Monday, WebRun opens your saved Coolors palettes, takes the text and background pairings you care about, runs each one through the Coolors contrast checker, posts a pass and fail table to your Microsoft Teams design channel, and pings Telegram whenever a core brand pairing drops below the level you require.
How do I check my brand colour palette passes contrast requirements?
WebRun audits your brand colours every Monday. It reads your saved Coolors palettes, runs the pairings you nominate through the Coolors contrast checker, posts a pass and fail table with every ratio to Microsoft Teams, and pings Telegram whenever a core brand pairing falls below your required level.
- A new palette is contrast checked in the week it is created
- Designers see the exact ratio for every pairing, not a guess
- Failing brand pairings are flagged before they ship into product

Questions, answered
Will it change my palettes?
No. WebRun reads your saved palettes and runs the contrast checker. It never edits a colour, deletes a palette, renames a collection, or publishes anything to the Coolors community.
Which pairings does it test?
The ones you nominate, for example body text on background, button label on button fill, and link on card. Naming the pairings keeps the table short and matched to real product surfaces.
What level does it check against?
The level you choose, usually a 4.5 to 1 ratio for body text and 3 to 1 for large text and interface elements. Anything under your chosen level is listed as a failure at the top of the table.
