No reflection on the source but it came with the "goop" and I believe measured out properly. Mine was not the only one done in the gun metal blue and results were similar I told. I'm thinking UV and some colors don't mix so well.

: Here is the color chart for Jacquard's acid dyes:
: http://www.jacquardproducts.com/products/dyes/aciddye/colors.php

: It sounds like your blue dye was not made with a stable pigment,
: but a combination of different colors. You shouldn't have that
: problem with browns, but contact Jacquard to be sure that you've
: picked good colors.

: I used three browns and a sponge to do mine. Start with the
: lightest color, and work to the darkest color. I have had no
: fading at all, but what I have had is the nylon turning more
: amber, which makes the lightest of my color darker, and lessens
: the contrast, so keep that in mind.
