Why wont this particle emitter changes colors correctly?

This script changes the color of a particle emitter, but its only changing when I get to the 7th color?

Edit: I tried changing what colors it switches to and found that when I add one color it makes the other colors not work and vise virsa??? How do I fix this??

local colorone = Color3.new(255,255,255)
