|
| https://www.inclusivecolors.com/
|
| - You can precisely tweak every shade/tint so you can incorporate
| your own brand colors. No AI or auto generation!
|
| - It helps you build palettes that have simple to follow color
| contrast guarantees by design e.g. all grade 600 colors have
| 4.5:1 WCAG contrast (for body text) against all grade 50 colors,
| such as red-600 vs gray-50, or green-600 vs gray-50.
|
| - There's export options for plain CSS, Tailwind, Figma, and
| Adobe.
|
| - It uses HSLuv for the color picker, which makes it easier to
| explore accessible color combinations because only the lightness
| slider impacts the WCAG contrast. A lot of design tools still use
| HSL, where the WCAG contrast goes everywhere when you change any
| slider which makes finding contrasting colors much harder.
|
| - Check out the included example open source palettes and what
| their hue, saturation and lightness curves look like to get some
| hints on designing your own palettes.
|
| It's probably more for advanced users right now but I'm hoping to
| simplify it and add more handholding later.
|
| Really open to any feedback, feature requests, and discussing
| challenges people have with creating accessible designs. :)

| I get that you say it is for advanced users, but I think a "how

| Thanks for the feedback! Yeah, I appreciate there's a lot of

| Last year, PlasticList found plastic chemicals in 86% of tested

| FDA still allows levels roughly 100x higher than Europe's new
| standard.
|
| That seemed solvable.
|
| Laboratory.love lets you crowdfund independent lab testing of the
| specific products you actually buy. Think Consumer Reports x
| Kickstarter, but focused on detecting endocrine disruptors in
| your yogurt, your kid's snacks, or whatever you're curious about.
|
| Find a product (or suggest one), contribute to its testing fund,
| and get full lab results when testing completes. If a product
| doesn't reach its goal within 365 days, you're automatically
| refunded. All results are published publicly.
|
| We use the same ISO 17025-accredited methodology as
| PlasticList.org, testing three separate production lots per
| product and detecting down to parts-per-billion. The entire
| protocol is open.
|
| Since last month's "What are you working on?" post:
|
| - 4 more products have been fully funded (now 10 total!)
|
| - That's 30 individual samples (we do triplicate testing on
| different batches) and 60 total chemical panels (two separate
| tests for each sample, BPA/BPS/BPF and phthalates)
|
| - 6 results published, 4 in progress
|
| The goal is simple: make supply chains transparent enough that
| cleaner ones win. When consumers have real data, markets shift.
