Readability
Text and background pairs must be legible on the real page. A style guide pass is not enough.

The color layer that tells a buyer what is safe to read, trust, click, correct, and finish.
Definition
A Color Contrast Trust System is a website color system where contrast, CTA color, proof accents, form states, and CSS tokens are assigned by buyer job.
The point is not to make the site prettier. The point is to make the page feel controlled. The buyer should know what to read, what to ignore, what to trust, what went wrong in a form, and which action matters.
Color psychology is about what a hue suggests. Color contrast trust is about whether the page can be used without friction. A brand can understand the first and still fail the second.
System parts
Text and background pairs must be legible on the real page. A style guide pass is not enough.
The primary action needs one color rule. Secondary links should not pretend to be primary buttons.
Proof needs visual weight, but proof should not steal the action color.
Focus, error, warning, disabled, and success states need distinct colors and accessible contrast.
Colors need names by job. Tokens prevent five blues from quietly becoming the brand system.
On Shopify, PDP, cart, checkout, and apps must feel like the same buying path.

If the page has inconsistent colors, first decide the job of each color. Then change CSS. Otherwise the patch becomes another shade of the same problem.
