mixing plastic colors?

i am trying to mix a plastic color called powder blue. it is light blue or baby blue color? can anyone tell me what colors to mix to come up with this pale blue color? any help would be great. thanks

It would help if you posted a pic. There are so many different colors out there there is no way of knowing. I get people all the time callin me wanting somthing in "red shad" the next question is which red shad there are over 10 companise now that make that color and there all different.

thanks i will try to take a pic and post it

Trial and error method . Mix enough plastisol for one pour and or one shot 1/4 to 1/3 cup put 3 drops blue and 6 drops white . Should give you a slight opaque powder blue depending on colorant pigment density.
