This is a more gruesome bruise, which can be used as a black-eye. Dab dark-red, purple, and bluish-gray makeup on skin, in that order.
This is another bruise recipe. Add some grey with a touch of red on the skin, in that order.
A grass stain can be achieved by patting on yellow, brown (or red), then green, that order.
A gravel burn can be created by dabbing on blue then green, then adding some brown.
