Ah ha! So that's why when I mixed all the jars of poster paint together, I got brown instead of white......or even black. Also a ration of crap from Mrs Midyet.
Superb explanation, linknoid. That explains a lot of things that didn't quite jibe with what I'd been taught. Thanks for taking the time to expand on it so we could all understand it.
YOU, yes you, lurking out there. You didn't know that either, did you? You were waiting for me to make a fool of myself so you could find out the straight skinny. That's OK, I do it all for you. Happy New Year.
btw- Great link...I'm saving that one.
