Sharpie has two types of pens now. The regular ones do not have as
good of an ink in them as they used to. The old ink is still available
and is sold in the Sharpie Industrial pens (now called super permanent
ink ... funny, I thought permanent was permanent ;-) ). This always
worked ok for me (not really great, but ok). I always used black but
never tried other colors (hmmmmm).
