[Minor]: Web site uses very low contrast which is not inclusive for older eyes

[rofrano]

Link to page(s) with issue:

• Entire site but here are some examples:
• https://planning.wiki/ref/pddl/domain
• https://planning.wiki/ref/pddl/problem

Quote of current error:

Your web site isn't inclusive of people over 40 or whose eye sight isn't what it use to be. Dark blue, brown, and dark green on a dark grey background is extremely difficult to see. The colorful pddl examples would be very easy to see if you had the background set to white. I'm guessing even young people can't read dark green on a dark grey background.

When I ran your Domain page through WAVE (Web Accessibility Evaluation Tool) there were 451 Contrast Errors on that single page alone. You can see the report here wave.webaim.org

Proposed correction:

Please consider using a theme with lighter colors and more contrast or give an option to toggle a light/dark mode. My eyes will thank you.
