IMO those are exceptional mutations. Even if you breed 2 of the same kind you may not get specific patterns like the parents. Never the less the offspring has that mutating gene and will show similar coloring.
A marble is when the fish changes color from it's original color when young. Most often marbles turn into a pale/whitish pattern. Recently I came up with marbles that sort of turned pale and eventually became reddish (from copper).
I don't really like marbles because it's unpredictable. They change color patterns that I like. Some marbles change partially while others may change totally....... I don't know how to best describe it - unpredictable.
I wouldn't mix yellow to red. For yellow to appear you need non red gene (Nr) which is recessive towards red. It would be more probable to mix marble, red cambodian, and yellow or something containing such genes.... I'm not sure. I don't think I've ever seen one fish having both yellow and red colors. So I assume that those colors don't mix - you either have one or the other... but then again new mutations may occur.... who knows.
