Can the default colors for the gemini http site be changed?

[Drew DeVault]

Emphasizing that Gemini user agents can adjust the presentation to suit
the user's preferences is entirely fine, but making accessibility
choices which discriminates against users with visual impairments is a
much less agreeable choice. The site should strive to be plain and
readable.

It's pretty accessible through my Gemini portal, if anyone needs it:
