It's doable with some patience you would need a pyrex cup with the one color and the injector with the other and alternate but to do this right a twinjector with the cross bar removed and each injector pulsed will get the job done.
My opinion is instead of getting a myriad of responses and no real answer look on youtube for guys posting their paint schemes most list or tell you what colors are being used and why - I think you'll get a better understanding of color use and you will see the colors they use and how they use them, remember pictures/videos tell a thousand stories. As far as thinning no paint is truly A/B ready and I think you would hurt yourself trying to find just the paint that is, Createx has some very good colors in several different paint lines, I use their 4012 high performance reducer.
I hear ya maybe he could of handled it better who knows, but just an FYI I got this cheap little mixer off of amazon if you notice it has several attachments but the one that stands out and works like a charm is the one with teeth it breaks up any solids pretty quickly. Works great for Airbrush paint as well. But note that was with 2-4oz bottles have not tried any bigger yet.

I tend to agree with Frank on this settling is par for the course, all these materials we deal with will do that you prolly got some that was not a best seller and has been on a shelf longer than most but it will come back with a little effort why should they pay to replace something that is doing what it is known to do and easily reconstituted?
To be honest you should be more concerned with what your entitled to for your time and material not what he's paying someone else after all you need to make money at it, if your product is superior then you should be in good shape trying to undercut for the sake of business is a lose/lose situation. Feed him a couple samples and let him come back to you. Sure would be nice to get a sample of what he's using to help compare. Good luck!
If your hand pouring an open mold you really can't beat Lurecraft's trick worm it's easy to pour and they come out very nice and the price is right you can buy 4 molds for the price of one cnc mold.
Yep agree with the above statements concerning plastic kinda why I avoided the suggestion, but as stated do a little research here there is a thread on the subject of plastics I will however tell you to stay away from janns netcraft for molds as they are dangerous. If you have no plans on selling anything then based on many positive reports I would consider DoIt's new line of entry level molds they will catch fish all day and the price is right.
I found that starting with medium plastic was the way to go as most baits will work fine you can buy softener and hardener if you need an adjusted formula. All the suppliers have their good and bad so it really comes down to what molds you like and then see if they have the colors you think you'll like. I personally bought pre-made colors as opposed to buying blue, red, yellow and mixing them to obtain a particular color you have many things on your plate to learn and making/mixing colors is probably left for when you become more familiar with the process. 5 gallons is recommended both for cost savings and the inevitable bad batches while learning which leads me to suggest that you buy a bigger bottle of black colorant as thats what you'll wind up doing to at least rescue you botched colors
I've been busy for too long now but I see they have a few new products, the one is called Candy20 aniline-dye but the one that got my attention was the new 4030 intercoat and balancing clear it seems to indicate that it assists in working with soft plastics, now mind you I'm not suggesting that they are talking about plastisol but just wondering out loud if it has potential for our applications oh and I'm thinking hard baits too so thats why I posted here
Watermelon, green pumpkin/pumpkin, black, white, junebug/purple, chartreuse but I would add some pearl powders since they go a long way and would take those six colors and multiply them many times over with variations.
