You could easily pull off silver or blues (but that's best if you don't have a lot of pink or yellow underneath the pale. I'm like a cream rose because I'm frosty-pale but yellowish). You could certainly pull off light, dark or bright colours. Pastel colours e. g. mint, baby blue or lavender could look really good if you don't have much colour in your skin (e. g. red cheeks).
hmm... I dyed my hair many colours, blue. purple, cyan, mix of all these, silver blonde. I think if you put a picture everybody could have better opinions because it depends on your face too. I think colour is taste. with a very pale skin I would tell red, but then you may don't like that and there are other colours that are good like green or a mix of cyan and blue or even pink. but you have to decide how you want to look first. every colour is different.
