Moved from the WPCampus accessibility report issues on GitHub, see:

  • Severity:
    • Low
  • Affected Populations:
    • Low-Vision
  • Platform(s):
    • All / Universal
  • Components affected:
    • Edit Media

Issue description
On the Edit Media page, the "Scale" button has insufficient color
contrast, below the minimum threshold of 4.5:1 for text:

Scale button: #fff (white) on #0085ba (light blue): 4.14.
Sufficient color contrast is important for users who have low-vision or
are color-blind, because text with a low contrast ratio may be difficult
or impossible for such users to see.

Issue Code

    .wp-core-ui .button-primary {
        background: #0085ba;
        color: #fff;

Remediation Guidance
Darken the blue background to match the other blues on the page, which
have sufficient contrast relative to their white text.

Recommended Code

.wp-core-ui .button-primary {
    background: #0074a2;
    color: #fff;

I am adding needs design as whilst this has some ideas, let's also get a decision on this. I agree 100% it should be worked on for 5.3.

  • Status changed from new to closed

Going to close this in favor of #34904, which has some mockups we should implement to cover both button color and better focus styles.

@chetan200891 Thanks for your patch here — do you have the time to look at patching 34904?
