Dynamic Block Coloring
What i'm proposing is so when you paint an entire grid using Shift+Ctrl+Middle-Click (but not exclusive to Shift+Ctrl+Middle-Click can also be used with Shift+Middle-Click and Ctrl+Middle-Click) and only certain colors stay and others change. for example that you have a ship and it has blue, black, purple, and green but you want the blue to be red and black to be white and green to be orange and purple stays the same. Right now there is no way (that i know and that is quick like 1-3 button presses to paint an entire grid in a snap) for you to make certain colors a different color of your choosing and also have it where you can change specific block’s color say for example you want to turn all the conveyors on a grid to blue and turn all passageways to red and spot lights to black but leave everything untouched and stay the same color and also and undo option too. it honestly would save on time for painting the blocks. so i say Keen please make it happen.
