Yes, I thought similarly; the difficulty of overpainting light over dark seems unique to airbrushing in a way that you just don't encounter with graffiti murals etc.. Certainly I've never read of urban artists talking about colour shift in any of the art forums I visit. Or witnessed bluish edges on their white outlines. Perhaps it is, as you say, to do with paint volume. Curiouser and curiouser!
Maybe aerosol is more opaque to begin with, then when you add the larger volume of paint that they throw it avoids the shift better? That’s a question not a statement . Sent from my iPhone using Tapatalk
I think the volume definitely has something to do with it, I will ask Gear if he knows about it and get back to you if he responds!
Thanks Mac. I’m just spit balling ideas as I’m trying to figure out colour theory, I’m very much in the early stages . Sent from my iPhone using Tapatalk
It all has to do with coverage. If you spray a thin white line on a black background, it is blue. If you spray the same line a couple times, it is white. But the edges of the line are not covered so they keep a blue glow. If you tape the line. can you spray a line without the edges turning blue. It is a pity that there is no white paint. There is always some black in it. And then there are manufacturers that add blue to it so that the paint appears whiter than it is. Don't think they do that with airbrush paint.
Gear said there’s no effect with the modern thick high volume paints, so (as Erwin says) it’s about volume mostly!
That’s good to know. I’ve often wondered if I went back over the lines would it make it better or worse. Now I know. Thanks Guys. Sent from my iPhone using Tapatalk
