The dyes are not store exclusive; you can get any of the colors via achievement awards in game; with ESO+ you can dye your armor/costume as much as you want with any color combination you want. For ESO+ members there's no need to buy dye stamps from the store :-)

Also, on a rare occasion, ZOS decides to give people free ESO+ access for a while as a promotion, to encourage people to subscribe. When this happens, you'll be able to use those dyes for your costumes during the promotion, so you might want to keep them for another few months in case they do a free ESO+ week again.
I find the bigger issue isn't that the colors are only crown exclusive, but moreso that they are stamp exclusive. If the color you want is paired with ones you don't, or you use multiple different colors throughout your costume/hat setup you're kind of screwed. I'd like access to the nice orange, purple etc without having to use the other colors they are paired with. Not particularly concerned with how that would happen.
