Crackled ceramics
. . . in which case, I thought, it ought to be possible to create a material where the colour is a parameter. After a little experimentation I came up with a layered materail that is similar to benjzie's but with a single diffuse colour that is editable.
Oh, and I'm sure that it can be improved . . .

PS Please unzip the material file to get to the mat.zip version - that's experimenting with the packaging to have more useful file and Library names.
