Sounds crazy.  I always thought they made those colors either by spinning a twin/tri injector, or by pumping each injector a little bit. 

I have no idea if this would work or not, but how about This:

1.  Pick one color as your main or base color.
2.  Cook up the other colors and shoot them into something thin. 
3.  Chop up the resulting injections. 
4.  Cook up the main colors and quickly stir in the chunks of other colors. 
5.  Open up your injector and pour the mess into it. 
6.  Then inject your Club-O mold. 

It's the only way I could think of without an actual multi color injection rig, and the ability to pulse each color just a little bit until the mold is full. 

I saw this blog entry over on Yuma Bass Man, and I have to ask how do you make that color? 

I've never made a Club-O that color but...

Sweet Potato Pie - I recall it was red yellow orange, and black.  I looked it up and I'm not sure if Wave Worms still makes it.  The original was random blotches, blocks, or sections of the color, but the worm I found (Bass Pro knockoff) seemed to be a more streaky swirl. 

How would you make that?  I have a single injector and a two color laminate injector.  I think the orange, could be where yellow and red blend a little, but I still don't know how I would make it.  Does it require a 3 or 4 color injection system with some way to pulse each color just a little bit?  Is there a way I can make it with what I have? 

I have a 10 cavity 4 inch Club-O mold. I'd love to make some Sweet Potato Pie Club-Os, but I only make baits for myself.  I don't want to make a huge investment in more equipment.
