While working on my 100 blocks Chess project (link below) I shared the original project because I couldn't get the "color () touching ()" block to work properly. This project illustrates the workaround I came up with, using as few blocks as possible. Each Chess piece clone has a sprite only variable called "color", which is either white (0xFFFFFF) or black (0x000000). This variable can be passed to the "touching color ()" block, to detect collision with pieces of the same color. To detect collision with pieces of the opposite color "abs(color-0xFFFFFF)" is passed instead. In this demo, press Space to toggle white/black. All code by me (@kriblo).
