I'm going to pretend this thread isn't a train-wreck and attempt to give a serious reply...
I like colorful handles on knives. I own a lot of them, and one of my longest EDCs is a pink Spyderco Native. There were a few reasons I got it:
1) Money went towards breast cancer research
2) I like the way it looked
3) I thought people would be less intimidated by it than my other knives
For point three, it was very true. People would comment on my cute knife, or laugh when I was using it instead of reproaching me, or giving me sidelong glances.
However, there was one disadvantage with colorful knives...they stand out. People are more likely to notice my pink knife than my black/gray/etc.
I don't hide my knives, but I don't like announcing to strangers that I have one.
One thing I did with my Pacific Salt was to RIT dye the end so it wasn't obvious to the world.
