I really don't know enough about colors to help with that, but I do know that the large red flake will give a clearer/lighter colored bait a reddish cast. That's why I always add my flake right after the plastic kicks over, and then add my color, drop by drop, to see how the two work together. I have found that, for me, heating the flake while the plastic is being heated to 350 initially can cause it to bleed, and change color. If I were trying to match that bait, I'd cook a cup of plastic, add the red flake, and then pour some into two different heating cups, so I could play with the two different colors suggested here to see which one is closer.
