I have been looking for a good chartreuse paint, I dont think createx makes it! I was thinking of using the florescent yellow, but I would love to find an actual chartreuse color!

flourescent yellow on a white base is very, very close to chartreuse

I've not found a try chartreuse color, I use c-tex flo yellow over pearl white.   I've also mixed flo yellow and flo green to make chartreuse that to me is closer to the original color.

Createx used to make an actual chartreuse - yuck! - I think neon yellow is much nicer.
