I shot some blood red and opaque fluorescent orange ice plastics today. The red I needed to mix a couple colors from different sources to make it the color I wanted. I did a 4 ounce batch and didn't really have to load up on either colorant to get the tone of red I needed.
The orange....now that's a different story. It too ended up being a blend of colorants since I couldn't get the fluorescent from any one source to cooperate. I started with Caney Orange transparent nb at 30 drops thinking it might be enough tocreate the opaque. Nada. I added some orange hi-lites....about 1/8 tsp. Talk about electric, but not solid enough. I ended up having to add 50 drops of another heavier bodied orange to get this where I wanted it. It was mix, re-heat, shoot, check, mix.....but I got it down. The problem was with the small body diameter and extremely lithe tail section of this plastic, it would pale out to almost a pink without the second colorant.
The red is one super hot color in the northern portion of Minnesota. I have no idea why, but the guys from the Twin Cities north sure seem to smoke sunfish and gills on the color, but it has to be a really blood red. As mentioned I used two different brands of colorant and only 15 drops of each. One was fire engine red and the other deeper red with some black tones to it. The red turned out to be a snap. But now that this fading issue will have me keepeing an eye on the red stuff. I was using Caney plastic in both cases today.
