Re[2]: Colour Luminosity/Contrast for form inputs/controls/components

Currently SC 1.4.1 states:

1.4.1 Use of Color: Color is not used as the only visual means of 
conveying information, indicating an action, prompting a response, or 
distinguishing a visual element.      (Level A)

To me that would be better as:

1.4.1 Use of Color: Color is not used as the only visual means of 
conveying information, indicating an action, prompting a response, or 
distinguishing a visual element but when it is use a minimum level of 
4.5:1  to indicate UI/interactive components (Level A)

Something like that for example. Currently the closest thing I can find 
is G183 and a 3:1 ratio (which is too low IMO).

Thoughts?
