Okay this is going to sound stupid and a little off the wall but, I don't use names with colors I don't like. (Long story short, I'm a synesthete and I see letters in color) Even if the name itself is nice, if I don't like looking at it, I don't use it.
A few of these names are:
Ashley (blue, brown, and pink all muddied together in a finger-paint soup. Not my favorite)
Purvis (Sour rancid green smudged with stale pink with white and black dots. Not appealing)
Brittany (Brown, white, and pink lightly layered over each other giving it a muddy rosy color. Not the worst offender but yet another I don't really like color wise.)
Like I said, I know it's off the wall but, when I'm writing it's incredibly distracting.
