I discovered an event in clouds called "irisation"! (I hope I spelled that correctly) It's actually quite common, but a lot of people seldom notice...the colors are veritably irridescent, sometimes. I want to learn how to capture that!
I like it. I do have to say that clouds in any painting or picture really can add some needed character to it. Also, from a photographers prospective, they can help a lot with keeping glare down and making shots turn out a lot nicer.
I must say, I was astounded at the number of actual colors in even what appears to be a simple grey cloud! In subtle spectrum, of course, but it's every color of the rainbow! Truly! And thank you, by the way.
Yeah they aren't just gray..I think that is why they can be hard to paint. Until you try it you don't realize how complex some of this can be. It's like taking the herptile shots. I only get the shots I do b/c the herptiles are comfortable around me. If they didn't want to do something then I am just not going to get that shot.
