Prism - easy and fun puzzle [Evoland 2] (2 hints)

Some of you might now that I am an improviser. I've even founded my own school recently. I'm preparing myself for a new solo show called PRISM where audience will have influence of what is happening on the stage for the whole time. To promote the show I'm creating kind of a poster in GIMP. It's gonna be a standard prism picture but every color will have it's own character or personality with corresponding clothes' color. Every character will be based on my silhouette. I've just finished all the characters and since I have a spare copy of Evoland 2 I thought I could make a fun puzzle from it. So here it is. Good luck!
