Of course, if you’ve met IRL then you’ll have a different notion as to their aura; however, when I see certain names, strong images come to mind. Just a few to start:
bodypoet always makes me think of warm siennas and umbers, probably lit by candles
MamaTiger is similar in warmth, only I see a zing or two of high-energy black and orange stripes in there
Eve could only be iridescent pearl set against Chanel black
canvasshoes is white Keds and unbleached wooden floors, with electricity that runs only sporadically and is never missed
jinwicked is definitely that dyed orange/magenta hair color that works so well with strong features
Zenster is shiny aluminum set against endless sand and a strong blue sky
Libertarian reads muddy to me, and like some browns he’s earthy at some times and reflective at others (and sometimes just opaque)
NoCoolUserName is obviously ocean blue/green
tanookie has a lot of orange and yellow to me, sort of a jumbly pattern
Miller has always reminded me of a really pleasant tweed, with a good weave
Coldfire makes me think of fresh black asphalt that’s just been rained on
LynnBodini is butterscotch
