Part of shirt has faded to pink.?

You can dye the shirts. I doubt you'll get an exact match, but you can certainly get a close match.

I don't recommend Rit Dye. Rit Dye never stops rubbing off on your skin, even after many, many washings.

Procion dye is much stronger and color fast than Rit Dye. It is a permanent dye that doesn’t fade, like Rit does. It dyes fabric in a way that is like the manufacturer dyes fabric...less home-spun, and more professional.

You can buy blue Procion dye here, although many of the blues seem to be "Midnight" or "Cobalt". If you search thru this list, I'm sure you'll find a blue that works:

You do need Soda Ash to “fix” the dye. You can buy Soda Ash Dye Fixer here:

Oh dude, no more fabric softner and stain stick, chemical reaction like bleach, ok, take new shirts, wash thorougly in warm water, like 2 times, then get RIT Fabric Dye, can get at store, fabric shops, wal mart, ect, follow instructions to a T, little trick , when u dye shirts , add cup of salt, salt binds the dye to the fabric nicely, permanantly. Then when done 1st time, repeat process, will ensure EVEN dyeing.

No more fabric softners, or stain sticks, u can save the shirts this way
