You sure chose some bold colours! I really like UD shadows! For me, since I'm scared of my eye makeup looking OTT, I'd use neutrals with it. Like for Flash, I'd use something light like Solar White from mac in the inner corner, put flash on the lid and blend the solar white into the flash. and then I usually darken the outer v and in this instance I'd use either a) a dark purple (I'd choose Indian Ink a pro matte from my collection) or b) a black colour like dark soul/carbon.
Or I'd put flash on half my eye (prob inner half) and then the dark purple side from my Earthly Riches duo on the outer half and blend together. Or go purple/grey.
I also like to do purple/pink combos.
Sorry I've got no suggestions for Flipside as I"m not a blue/green e/s lover.
