Sure. I'm not saying there isn't diversity either. But for women, here's your cast:
White blonde, most with blue eyes: Karrin, Molly, Charity, Mab/Titania, Aurora, Ivy, Georgia, Luccio (post-swap), Gard, Lash (initially), Sarissa, Anna V, Hannah, Justine, Elaine, Kelly Hamilton, Abby, Monica S
White brunette: Lara, Inari, Tania, Natalia, Elisa, Madeline, Lacuna, Tess, Deirdre, Margaret, Maggie, Esmerelda (Eebs seem Spansih rather than Latino), Helen B, Lydia (Cassandra's tears), Kim D
White exotic hair: Molly (dyed), Maeve, Jenny G, Lily
White redheads: Lea, Andi
Not white: Susan, Martha, Ancient Mai, Tera, Bianca, Arianna, Olivia (?), Lydia S, Yoshimo
Am I missing anyone? I'm sure there are some more, especially one-off characters.
Anywho, of the not white selection, you've got five that appeared in one book each, one that appeared in two, another that appeared in three, and one that appeared in five.
Combined, the same number of appearances as Murphy alone.
Lucio's new body had Brown hair and dark eyes rather than blond, but it never actually says White girl that I can find. Id always pictured Asian myself, though I assume that has more to do with the Ghoul she ran with in DB. I honestly think it might have more to do with a general audience-side assumption that a character is white unless there is something more specific mentioned.
It's not all that different on the male side, though. Aside from a pair of Knights, LTW, "Lucky" and maybe Mac (Ive tried and failed to find confirmation either way, I always pictured him black myself), there was a strong preponderance of generally white men (hair color not being a significant delineator on that side). Of course, there was a strong preponderance of Catholics, racially pale Vampires, European mythological figures, and the overall Council membership that has always been noted as being overly skewed toward European. The only groups that should actually /be/ represented by anything like the real regional ethnic distribution would be the Alphas as generic college kids, and Marcone's organization. And maybe the KotC, which are already about as diverse as a 4-person sample size can be.
PS I dont think I understand the distinction between the Eebs being counted as white but Susan not being. Admittedly Ive always struggled with the fuzzy distinction between "White" and "European". I mean, even old Luccio would have been 18th century Italian and a reasonably far cry from the nordic European in terms of coloring.
