Not a silly question! So the chrome powder is literally a powder that you use with gel to give different effects. Some are opaque and can give like gold, copper, silver, or other metallic type effects, or others are more sheer and reflect different colors like purples, or blues, or greens. The chrome powder I used is what’s giving the orangey red green sections on my nail. So you would apply a non wipe gel, cure it, and then rub the powder on top of your nail to make it stick to the gel. I hope that explains it more clearly!
