Valspar paint crystals - made in silver/gold glitter to add to any color paint. Our baby's room is grey so we added silver. Here is a perfect picture of the final outcome. The glitter package recommends 2 packs, per 1 gallon of paint (for LOTS of glitter). We added 4 since it was hard to see in the paint container. We don't regret it one bit! It's still hard to see on the wall unless the light is right. It doesn't add a texture to the wall so I say there's no such thing as too much glitter!
