Following the Web Content Accessibility Guidelines (WCAG) for contrast

[Sawuare]

I noticed some issues of low contrast on the website. Adequate contrast is necessary for all users, especially users with low vision. I think following the Web Content Accessibility Guidelines (WCAG) for contrast would fix the issues and improve accessibility. Specifically, I think these criteria should be met:

• Contrast (Minimum)
• Non-text Contrast

This article helped me understand the criteria.

Some of the issues I noticed are described below; this is not a complete evaluation. I used this checker to check contrast.

This color combination on the homepage (and elsewhere) has a contrast ratio of 2.83:1 and fails Contrast (Minimum).
See the check.
Making the background darker is the best fix.

This color combination on the homepage has a contrast ratio of 2.19:1 and fails Non-text Contrast.
See the check.
Making the background darker is the easiest fix.

This color combination on the downloads page has a contrast ratio of 4.22:1 and fails Contrast (Minimum).
See the check.
Making the background darker is the best fix.

I tested making the backgrounds dark enough to meet the criteria; they look better!

Maybe the criteria should be required or recommended in the wiki.
