Yes, they dry much darker and for this reason it's difficult for me to mix up colors. I guess over time it will become second nature but starting out it would be really useful to have a reference guide for mixing colors. I would love to make a color mixing guide with visual or video and I just might but I would be extremely suprised if there isn't one available already... Has anyone ever seen or heard of a color mixing how to guide for Chefmaster Liqa-Gels?
