I've moved on from HexChat to Textual and have created a new color scheme there. Leaving this repo here for preservation, but it will not be receiving updates.

Color scheme for Sublime Text and HexChat
Admittedly, this is a totally personal color scheme and I don't expect it to perfectly fit the needs of others, but just in case, enjoy!
Sublime Text theme created on TmThemeEditor and loosely based on Base16 Ocean Dark (hence the ocean-y theme here!). Looks great with Spacegray, which I highly recommend.
HexChat color scheme has some deviations from the Sublime Text theme for a bit more variation if you use colored nicks, but background, foreground, selection, and many of the colors still match.
