I was thinking if we could have advanced paint; Painting on all 4 sides of a brick.
It should work on all bricks in the Brick, Round, and Ramp categories. I don't if it would work in Special bricks (Different colored vehicle spawns could cause a problem with colored vehicles, different colors on a tree could be impossible, and possibilities of errors and glitches on different bricks that make another Category, such as Zone, Wedges, etc.)
This would really help in building, such as in houses, making the inside have different colors than the outside, and other things. (Don't judge me, it was really for houses when I came up with the idea.)
Please make it if possible.
