I was watching some tutorials on air brushing models and the guy used a black base coat then painted white into it at various spots to show the lightening of the color over time. I usually paint a red primer but could doing the white paint in certain areas still work, or is that best only done with black base coats?
Its called black baseing, several members here use it. I have only seen it done with black, hence the name. I guess red would possable work, i think the main thing is the background colour needs to be darker. But the paint you then apply should be in thin coats and i would imagine the red would effect the final colour.
Doogs Models has the best video tutorial on this technique. It works well on gray aircraft models. It can work on armor. The final color coat is usually thinned well beyond 50%.
Base coat black…mottle coat of finish color allowed to fully dry…then very thin final coat
Like anything it takes practice to get right.
I almost always base coat in red as well I’m thinking about changing that up on the next build. I have used red then faded some upper spots with Tamiya pink before and it’s looked good after
