If the stuff is made of Cordura there are a bunch of guides online for painting them, from Krylon spray paint to using a cloth rag to dab at it. It may not match your tiger stripe, but ultimately you get the control the color scheme. I've never done it myself (I have made costumes & weapon props for films) but the key seems to be many
many light dustings. you want the paint to soak in, not a think skin that'll flake off.
