Honestly, that is such a subjective question. It really depends on what your mind's eye finds appealing. I guess I would go on Morphmarket, plug in Pastel Orange Dream as a gene and keep it set to 9 genes, then search all and see what comes up. There should be tons of OD Pastel combos to look at and then when you see something that suits your fancy, find the male that carries the genes you need to make that combo.
Best of luck.
