First of all, thank you so much for the resource of this forums. I have learned so much from here. I have learned answers to questions I didn't even know I needed to ask. So, a little background on me. I'm fairly new at this hobby and I'm still in the beginner stages. I'm also learning how to airbrush and I want to airbrush as a painting tool outside of model building as well as painting my models. I am currently trying to collect all of the Vallejo paints, and some Tamiya paints. My professional background is a stucco plasterer. Our favorite type of stucco finish right now is acrylic stucco. I've been to where they mix the dye's for our finish material and what they do for mixing colors is they have a contraption that holds bulk color and will dispense a measured amount. They have a chart that tells how much of each color to dispense to create the color needed. This makes for a very controlled dye color for professional use. I want to know if I could set something like this up for myself. Has anyone tried and what are the limitations? I was at a general hobby store yesterday and saw that they have big containers of color for like $15 a bottle. I found a couple online resources that have all the color for every model paint company and how to mix them from the prime colors so I think this would be a very cheap (comparably) way of getting all the colors I want. Here are the online resources so you have a better idea what I'm trying to do. First, a cross section of different model paint color schemes: paint4models.com next is a color mixer: trycolors.com What you do is go to the first link and pick the color you want. Say the model calls for Tamiya XF57. You find that and look at the RGB code, which is E0C895. Then you enter that into the second link, the trycolors.com and it tells you that to make that color you need 4 parts yellow, 4 parts red, 3 parts cyan, and 5 parts white. So much experience here, I'm sure I'm not the only one to think of this, so maybe you could steer me one way or another before I invest in a bad plan =)
