He wanted half blue, half red. Its easy to apply. Colors are vibrant but fade more and more everyday. This is due to the rub off of product. But my son is happy, so I am happy!
A little goes a long way... the product doesn't stain and is easy wiped up. It also washes out of clothing (it does transfer!). We have red, blue, purple, green and orange. We have used all the colors except green and orange. We will use those soon.
