Re: Pastel BEL questions..
i dont know what it does to very white BELs, but pastel seems to at least do something to the BELs that are not completely white.
from all the pictures i have seen so far, the snakes dont really get darker because of it, but do get more yellowish. purple passion versus pastel purple passion and super mojave versus pastel super mojave show differences. super mojave has the grey head and a white body with a little bit of grey still present, with pastel added the head gets lighter and the snake gets some slight yellow, sand-like color. also, with mystic potion / purple passion, if anything an added pastel wont make it darker, even might light it up a bit, but the blue/grey or lavender hues turn more into yellowish/sand-colored hues.
one thing is clear: an added pastel wont make it less beautiful. But its unclear how easy it would be to spot it in a very white BEL. I would say the extra pastel in the pairing will just make the clutch more interesting, its a bonus, not a problem. I would just go for it, and prefer it over the basic butter to mojave pairing.
Maybe you get very lucky and get two very white lucys, one with a cold almost blueish white and one with a warmer yellowish white. Now wouldnt that be cool? Or maybe you figure out that they are almost identical but you can see it in their eye-color.
