It's my understanding that some of her offspring could be "cleaner" looking than others, but that they would all tend towards the browner side of the spectrum. If she were mixed with, say, a spider, her offspring *could* be bumble bees (it's a genetic lottery), but they probably wouldn't be as nice looking as DrDoolittle's bee (check out her pictures, that snake is gorgeous!). Just keep in mind that they wouldn't sell as high as a bright, clean bee- but breeding shouldn't be about profits anyway. If you want to give breeding a shot, go for it and sell/give the offspring to friends as awesome pets or keep them for yourself. If you're interested in breeding as a long term hobby or maybe even a business, save up for the individual snakes that blow your socks off, rather than the least expensive example of the morph (not that I'm suggesting you would do that! Just general advice)
Also, if feasible, shop at shows and expos. Pet store chains have crazy markups! The one near me (a smaller chain) had a hatchling male pastel for some $225 😏. Shows are great for finding very nice individuals for reasonable prices.
Best of luck! She's cute!
