I need a blue stain removed from my grey-ish PE uniform?

Question

Basiclly what the title says, I think it may perhaps be dye of some sort from my purple shorts, although im not sure.
Are there any quick methods I could use within an hour to remove the stain without leaving bleach marks?
[The stain is splattered on several different spots]

The best thing I've found for ink and other mysterious ink-and-dye-like stains is plain, cheap aerosol hairspray. Spray it on the stain and rub gently. Worse case scenario - it doesn't work and then you wash it out.
