Super cute little guy! I hope he settles in well for you!
I was a little confused by the title but the deli cup photo clears that all up! I didn't quite understand what you meant by the (Pastel/butter). I'm hoping to hatch out a little cutie like him in the future. But that's a bit aways still.
A bit of genetic trivia for you!
-Lesser and Butter are thought to be line bred versions of the same gene or extremely similar. It's just good practice to keep calling the genes by the particular line in case you do end up looking at breeding in the future. So even though they might be the same, just refer to any offspring with the gene as lesser. If the female was a butter, then that's a different can of worms because you can't tell which gene is which in most cases and just have to say Lesser or butter.
-Orange Ghost is it's own recessive gene. In some cases, but not all, it is compatible with 'hypo'. This is another gene where you ideally want to keep it in the same 'line'. But especially if you don't end up with a compatible hypo, you would end up with normal looking babies that are double het for orange ghost and hypo.
