I want color suggestions

[mirisuzanne]

There were several requests on social media, eg:

• https://front-end.social/@sia/110843581180299706
• https://mastodon.online/@atjn/110838201526464001

The user would select a background, and then ask for a suggested text colors. The two forms of suggestion requested are:

• suggest a hue based on color theory (e.g. complement, triad, etc)
• suggest a contrasting color

The latter could either suggest black/white, or scale the lightness of a color until contrast is achieved.
