Like Mark said, hard to know without a picture. One of my favorite red colorants is cherry red from spike it. That, plus black grape would probably get you something really nice.
If I had to choose just four I would start off with watermelon, green pumpkin, junebug/black grape, and black. Flake would be black, red, blue and green.
Welcome to the site! For someone who doesn't speak/type English as their first language you do it quite well, better than many kids state side! Like Jeff said you're unlikely to get many responses here but if you do find the information you're looking for I wish you the best of luck! I've caught a few snakehead myself in the canals down in Florida and they're a ton of fun to catch and really good eating as well.
I personally will never use anything other than bead blasting media ever again. It's just that much better than salt or the HD additive from Do it. The only trade off I've encountered is some scratching of the injector but that is one I'll take time and time again for the quality of the baits you get.
I use remelts as much as possible just to save myself some money. If they don't turn out nice I just add a lot of black haha. Smallmouth pretty much covered everything else for you.
Have a buddy who uses the spout to fill up his injector and then injects his molds and whatever is left he pushes it back into the pot. Remove injector tip, fill and repeat.
Dyes make great baits as long as you don't put them with baits of a different color or laminate your baits with any other color than black or it will bleed through and change it. Don't be scared away from bleeders, they're great! You just have to be mindful of how you utilize them and realize they do have limitations.
Is it black on top or a dark green pumpkin? For the bottom I would try some orange with a couple drops of pumpkinseed or brown and then I would throw in some gold pearl or copper pearl, hard to tell from just the pictures.
Ispikeit.com is about the cheapest I've found and it's all very high quality. Senko colors for me are simple. Watermelons, green pumpkins, black. That's about as varied as I get. I did make some baby bass laminates last summer that caught a mess of fish but that was more out of boredom that those were created.
It's definitely a Big Texan pit boss. Get some dark brown or dark green pumpkin skirting material and some orange/pumpkinseed skirt with green flake and you'll be in business.
Holy crap...the work some of you guys are able to achieve is absolutely incredible. Wish I had the skills/knowledge to build something like that! I went in another way with my knowledge which would be medical knowledge on how the body works/why it doesn't/how to fix it when it's broken but would LOVE to when day be able to learn how to do some metal working and wiring when I retire many many years from now haha.
A little off topic but a good trick nonetheless, a good way to prevent scorching in your cup, especially if you're reheating a lot is to take a piece of cardboard and cut it to the size of the glass in your micro. Place that piece of cardboard on top of the glass and you're good to go. Not sure why but it gives you much more even heating of the plastic and really decreases your chances of scorching your plastic.
