Your post is seen on https://talk.tiddlywiki.org/ but no one can reply you there!
Regarding your questions: Mat answered correctly your questions.
I really welcome and encourage you to work on TW palette an area needs more attentions!
There are several good previous work you can find in Color play
- http://j.d.palette.tiddlyspot.com/
- My TiddlyWiki — a non-linear personal web notebook
- Bricks — CSS Construction Set for TiddlyWiki 5
- Customization of TW5 4.24 — a demo TiddlyWiki ( TW v5.1.22)
- Plugins — Utilities for TiddlyWiki
Also see Color Play — playing with colors and palettes in TW
Difficulties: There is no few base colors to adjust them and color pallet generate shades accordingly for all UI elements
Dreams: Have a UI with 3-4 or maximum 5 colors to set and see the color scheme
Colorplay is an effort to implement the above dream! It is partially successful.
Lets continue this discussion here: [tw5] Selectors (and Colorplay) - definitions and examples?
