Each offspring of two het caramels would have a 25% chance of being a caramel. Whether or not you get at least one out of any particular clutch depends on luck and how many eggs you hatch but at least with two hets you have the chance.
Back to the question of breeding a het caramel to a het albino. Combs Reptiles is correct per the general assumption that albino and caramel are two different mutations of unrelated genes. However, I've yet to hear of anyone actually breeding the two morphs together to be sure. There is at least a chance that they are alleles (two DIFFERENT mutations of the SAME gene) and the results might be something other than expected, possibly producing 25% phenotype caramel that is genotype of a double het. Sorry to confuse things, probably best to just go with the generally accepted answer for now as it appears to be most likely to be correct and the allele theory is only an outside possibility.
