Hi family, hope you're all well! I'll be part of a street festival where there will be a graffiti art show and me with the airbrush. Cause it'll be a 4 hour session for 3 days I'm thinking I'll go for something monochromatic, probably a Bob Marley portrait. I've once read somewhere that you can make a mix of some colors, can't remember which, and get near the sepia one. Anybody has any info on that?
