I know being a "newbie" here I probably shouldn't stick my 2 cents in here, but having been an airbrush artist for over 20 years, I'm gonna give you my opinion anyway.
Createx is the type of airbrush paint that is most easily acquired through craft stores like Michael's or Hobby Lobby, etc. but the colors don't really mix all that well, and the range of colors is pretty limiting.
ComArt paint comes as opaque or transparent colors, all the colors mix very well, and, if you're looking for a translucent color, you simply mix the transparent and the opaque colors together. Also, ComArt paints come in an extensive range of colors for both the opaque colors and the transparent colors.
Another pigment that you can add to your airbrush colors comes from Liquitex or Grumbacher it's a line of paints referred to as interference colors...I think these colors would have a great impact on lure finishes, because, e.g., I have one that when the light hits it in one direction, it's got an orange cast to it, but when the light hits it in another direction, the cast of color is closer to lavendar...on a wobble type bait, the color would have an eerie irridescent quality to it because it would be in a constant state of color shifting.
OK those are just a few thoughts from the peanut gallery.
