ProAiir Fluorescent colors (aka neons), though incredible in many ways, are some what translucent but ATOMICS are opaque! These are the same colors used in RAINBOW colors except the swamping of pink/purple. Primary colors are a lot more opaque. Atomics offer the best of both worlds with colors that go on opaque AND are brilliant in both natural daylight and under black light. Note in the "photos" tab the different looks you can achieve with a single application. Brilliance by day or night!

Think of Atomic colors as ampped-up primary colors with UV punch. The Atomic colors dry bright and vibrant with one coat!
