I like having nicely documented colors and color combinations in my design system.
Here are my 2 go to Figma plugins for that:

1. Variable color style guide takes your color variables and creates nice documentation cards.
I usually work my color scheme to make sure I can always use the darkest shade, with the lightest shade, and they have sufficient contrast to be used as text

2. Contrast Grid: feed your colors to the plugin, and it will create a grid of colors that you can combine, or not, depending on their accessibility contrast ratio when used together.

OKLCH Color Picker & Converter

OKLCH is a new way to encode colors (like hex, RGBA, or HSL)
