The issues with formulations of dyes is that final color is very dependent on time, temperature, and concentration of dye. If we put out a "use this, this, and this to get this," we'd have a bunch of folks who were disappointed because it turned out a half shade off due to 30 seconds too long or a few degrees off of ideal.
We will likely have some formulations to post in a bit.
We will indeed have some formulations coming.
We are also looking at dyeing at the press with some new technologies that don't affect the polymer in the same way as older colorants, and bulk dyeing afterwards.
You may indeed see the return of some colored skus.
Dyeing with liquid dyes does not weaken the polymer in any way. It also doesn't hurt UV significance, or have any other negative effect, really.
