Notes

Selenized is a colour palette based on Ethan Shoonover's Solarized with adjusted hues and lightness to decrease ambiguity and ensure readability in all conditions. For full details see the project page at https://github.com/jan-warchol/selenized/tree/master.

Selenized Light/Dark — Like Solarized, but better. Dark teal and warm sepia complement each other nicely. Selenized White/Black — Old school look with a little more contrast for high contrast situations (e.g. working outdoors)
