Resin art

I'm planing on doing an abstract resin pour on my next board. Question is, I really want to do orange, and blue in the job, but im afraid that they'll mix. Do orang/blue, green/red, and yellow/purple mix when side by side, resulting in not very crisp lines? Another question is, I am using 7.5 oz volan, so when I pour a line or two on a part of the hanging cloth, will it drain out, and get filled in by another color? thanks

 

I have done orange and blue just make sure you wait tiil the last minute to pull the resin off and try to scrape a area only once the rails draining has more to do with how hot you set it off on my opinion.
