There are colors that I find difficult to mix. Or describe ("a 2x4 under harsh sunlight reflecting off the neighbor's pale blue house"). Here is an example, I started at the bottom, and 15 steps later I gave up and used what I had. I should have stopped at step 9. Then I realized the wood changed color as I was moving up.
Part of the problem is that I'm trying to match a dithered color on an 11" x 17" print, and its not easy. I was going through the six questions, but ...
What do you do when the 6 questions fail you? One answer would be to just get the value right and go for it, which is what I think I did. Got a better suggestion?
