While I do like “flat” icons, color helps to make them more immediately distinct than each other, and thus less likely for neighbor icons to be clicked accidentally (like “lock alpha” for the eraser or colorize and vice-versa, times three), so I tried to just edit those icons for my personal use.
I’ve edited them on Inkscape, saved them, but MyPaint’s GUI still exhibits them as monochromatic.
They’re actually the ones I’ve edited, as I did one minor tweak besides coloring, so I’m sure it’s not simply that I just saved them in the wrong place.
Is there something on the SVG’s own code that needs to be edited for them to be displayed in color, or is MyPaint “forcing” them to be displayed monochromatically?
If it’s something on MyPaint, is it something that I can tweak on the decompressed appimage file? (I’m doing all this on an appimage release).
BTW, maybe that’s too unrelated, but I just remembered it seems that MyPaint is also forcing the GUI interface to be dark, unless I explicitly run the appimage in a command along the lines of “env GTK3_THEME=mylighttheme mypaint.appimage.” But to be honest, I’m not sure my environment variables are properly set, even though MyPaint seems to be the odd one out in this regard.
