Minor Colourful reagent doesn't change the colour of bleeding blood.

[pali6]

Bleeding works fine for me. The only problem I see is with blood trails and with fluids. The former I'm fixing right now and the latter would require me to make it so the blood reagent itself changes colour and then I'd have to also implement proper colour mixing for when differently coloured blood mixes. Not feeling like doing that right now but I might do it later.
