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??

wait(1)
local colorone = Color3.new(255,255,255)
local colortwo = Color3.new(255,255,255)

###The problem is you're using Color3.new and Color3.new takes arguments of three numbers between 0 and 1. Anything over that will give you a white or black colour. You need to divide each number by 255 to get your desired colour, or use Color3.fromRGB. Color3.fromRGB takes arguments between 0 and 255, which will get your colour without the need to divide.

Color3.new(85/255, 85/255, 1) -- 255/255 == 1 lol

Color3.fromRGB(85, 85, 255) -- No division hassle 

###On a side note, switch to :Connect() as :connect() is deprecated and should not be used in new work (line 76).
