On TV they certainly had dark 'leader' daleks and the grunts were all silver - of course all the William Hartnell and Patrick Troughton Doctors were in black and white, so we didn't know if the daleks outer armoury had a colour other than shades of grey as such.
I'm afraid I can't remember much about the 2 Peter Cushing films, but I don't think the daleks had lots of colourways. From what I can remember they were metallic, which for a race who abandoned emotion is exactly right of course.
