Tom, the black has A LOT of different remelt in it; hd, uv, different hilites, blue, black and purple baits, glitters... it's a big pile of junk! Thin appendages look grey if I shoot it straight up, it's an opaque dark smoke. To make the color on purpose I would probably start w/ 4-6 oz plastic, 2 drops black x2, 1 or 2 drops blue (or purple of your choice depending which way you want to go) x2, blue or violet hilite, .04 Canadian blue and blue holo string glitters. The red of course isn't straight up red either, and worked with scrap to match the following recipe: 4 oz plastic, 1/4 tsp russet pearlex, 1/8 tsp red .04, 15 or so drops red (non x2)- basically enough to pull it away from russet towards being red. Also a touch of violet hilite. 2 tubes and the swimshad pictured are shot with this recipe, everything else in this red color is worked from scrap.
