Build a colour file for Space Sarge. Start from a preset, adjust, then export. Load the file into the app under the cog, or send it to someone else to use.
Set the four anchors and everything else — panels, borders, muted text, tinted backgrounds — is worked out from them. Then fine-tune below if you want to.
The file is plain JSON. You can edit it in any text editor afterwards.
Part of Space Sarge. Colours only — nothing here is uploaded anywhere.
