Has anyone really experimented with changing or covering up unwanted/disliked color packs? Specifically modern synthetic materials. Options seem to be dye for synthetic like Rit dye. Doesn't always come out like you hoped. (submerge entire bag is standard method, but what about using spray bottles? Some packs may have high vis interiors you don't want changed) Spray paint, hard to tape off what you don't want painted, can stiffen fabric (sometimes that good). Thinned, brushed on paint, again can stiffen fabric, goes exactly (close enough) where you want it, takes the most effort and patiences. (would the thinner damage anything?) Then there are fabric paints, but not sure they come in colors I'd like or if they are designed to cover an entire object vs. painting on words or a design. All this can be avoided by not buying a color you don't like, but sometimes those are the cheapest.
