Hello Josh,
While that would be helpful, causes a bit of problem to WG too if we are more directive.

I think wording something like “contrast ratio between foreground and background” would say it all and applicable to text, UI components etc.,

Reason I’m saying it technology keeps changing every day and we cannot really predict what would come tomorrow.

Makes sense?

Subject: Colour Luminosity/Contrast for form inputs/controls/components

I'm looking at contrast requirements for a client regarding form controls, radio buttons etc for a client, and WCAG does not seem to specify them. It seems 'implied' that 1.4.3 is relevant and there are techniques that touch on the subject (G183, G182, G111) but nothing definitive like.

"If you have an UI component/input control, or radio button that a VIP user needs to see to select/interact with the luminosity requirements are x."

Am I missing something? Or is this something we need to address?
