Crosses can produce some beautiful animals and some not so vibrant animals. They are only good as pets, not breeders. Chameleons don't have morphs like snakes. The genetics aren't as defined and are closer to crested gecko style breeding. The only morph there is, I believe is the translucent morph in veiled chameleons.
I like east coast locales myself. Tamatave, Sambava, maros, etc. They range from duller reds, pinks, greens, grays, and juvenile blues while at rest to brilliant white, all shades of red, orange, yellow, black, juvenile blue, and both dark and light green. They make me drool. My prized Sambava male is green and pink with blue, grey, white, and sometimes purple bars at rest. When he fires up, he turns completely yellow and/or orange with white, black, red, black-green, black-blue, black-red bars. He can be any combination of those colors at any time when he is at rest, in between rest and fired up, and when fired up.
