Planning on Painting Something in Glow in the Dark Paints?

well, I bought the white, blue and purple, in tubes, invisible by day, glow by night industrial strength paints. The price was a good deal...shipping was fast. In the tubes they glowed thier colors nicley.        I was excited about painting my ceiling, nebulae and stars to glow while I slept. well, oddly, and even though I used a seprate brush for each color, and none overlaid, at night they do not glow different colors... too much, they all just look like various shades of the typical boring glow green color. The white and purple area I painted, glowed the least, the blue was the brightest but again, not in thier colors, but of glow green...so If ya just want something to glo in the dark fine. If you are looking to paint a mural, where things are to be specific colors, (and they also sold yellow, green and orange and red) available on Ebay.. forget it... you will be dissapointed...does wash off hands etc easily, waterbased.  So now I am just gonna paint my ceiling a midnight blue and staple a string of led lights, for my starry ceiling effect. also I saw on Ebay!
