If you have a look at the palette-manager edition: https://wikilabs.github.io/editions/palette-manager/
There are a lot of palettes, that have a WL at the end of the name.

All of them should have DiffText colours assigned. Some feedback would be welcome.

That's a reminder, that I should create a PR for all palettes. Since all of the core palettes have some missing elements.

There are still a lot of palettes that doesn't have diff-* indexes in the palette manager edition, like the two palettes:

• Solarized Light/Dark WL
• Solar Flare WL
• Spartan Day/Night WL

While those palettes have their own diff colors, which I think can be included in the PR:

• Nord WL
• DesertSand WL
• GruvboxDark WL
• Twlight WL

If they do not have the indexes in the palette, they use the default from vanilla. That is intended. But I will have a closer look. I have seen some problems with some dark palettes, where the text is invisible.

Add DiffTextWidget colors to Solarized, Solar Flare, Nord, GruvboxDark, DesertSand and Twlight palette to make them display properly.

Thank you for using a consistent method for adding new color values! Everywhere you have use 6 chars hex code! Keep going on!

I think only changing the foreground-colour is not enough. We have to take "colour blindness" into account.

Eg: this is "Nord dark WL" palette: Accessibility setting: Simulate: Protanopia (no red)

This is the same setting, that I use with my Palette-Manager edition, with the same Accessibility setting

The same screenshot for "normal vision"
