RitDye More Synthetic 7oz-Sapphire Blue, Other, Multicoloured

I have a light pink, 100% polyester winter coat. It is permanently dirty so i wanted to dye it dark blue. Do you think that this will work?

The directions on the bottle are so small that I can’t read them. Can you please tell me what they are?

I have a 60% cotton 40% polyester coat that I'd like to freshen up, is this the right dye for me?

Will this work on something black
