Dr Ph Martin’s watercolor paints

A while back my interest was piqued about the brand Dr. Ph. Martin’s watercolor paints. (ahem Barry Comer and Mel ) I am a bit intimidated. Liquid watercolors are new to me….are you supposed to water them down, use more liquid or use straight out of the bottle…..can you mix them….is it proper to use other brands in tubes or pans with them….this is a whole new world…all I can seem to do is make color charts, mixing charts….baby steps….

Any advice, guidelines, experience, tips…so forth, that can guide me would be so appreciated.

FYI: Fondue plates (often accessible for cheap at second hand stores) make great watercolor palettes. I will write the name of the paints right on the ceramic plate and they usually wash clean quite nicely.
