(Above) I carved separate blocks for each color. Sometimes I mix colors on the page (i.e. blue and yellow overlap to make green), but on this example, I did not do that. But I did carve for two colors on the same block when the colors would not touch (as on the middle block, above); I show these - and the variations below - to say, hey! I am still experimenting, and this is a messy process. Like life itself!
