My favorite are the two different purples, the turq,fusia pink, dark blue, and the brown

I'd pass and just go with the black only -- the other colors (except for dark blue) are useless to me.

Some like black, dark blue, and brown aren't really what I was looking for, but I like the variety.

Colors are nice, helps with studying and needing variety, but I did notice that most of the pens (except the black, red, and dark blue) would go in and out of using ink
