I like the one that comes with blockland, so i've stuck with it, i've only changed solid blue's color to 0.000 0.000 1.000 1.000, so its a perfect shade of blue, the actual blue has some purple to it, that kinda bothers me...
Yes the ColorSet chain is a little bothersome for me, especially if they have transparent paints, that's quite annoying, and the invisible spam is worse
