The "Matte" Theme is eye-catching. Nice name, Great idea to make it a series of themes with more colors for the tabs. Your red one is the most successful. Can a slightly less black version be had in the future? rgb(38, 38, 38) or rgb(51, 51, 51) for example.
Well I do try to perfect aesthetics. Your request is slightly out of scope so I recommend modifying my themes (see github) and experimenting yourself! I'm not sure if you are the same person who made that fractal theme but that theme's background is wicked.
