And nature hasn't CTRL+Z. There are things that we must live with. Gimp is a computer program. It -like others- may or may not reproduce natural certain behaviors of natural media, because it's a computer program and there's code behind the tools you use. Maybe you'd like to point us a program that already has that feature so we can see what do you actually mean with "transparent color". As other people pointed out, what you're asking for seems quite similar to the substract mode, that is already available both as a layer blending mode and a blending mode for the brush and airbrush tools. And the alpha channel handling is quite the same that other programas have (like the acclaimed Adobe Photoshop). Could you please try to explain in a more accurate way what do you need? As far as I could undestand, it looks like you want to paint with air, wich sounds pretty funny. _______________________________________________ Gimp-developer mailing list Gimp-developer@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
