en to stick with it. That is, while 
I had two reds, if I used the warm one for one thing in the painting, I would 
tend to want to use that same red anywhere I needed red, to aid color harmony. 
And this did not really introduce any major hardship. It is true that mixing a 
good orange was a little trickier if I was using the cool red and yellow instead 
of the warm, but I found I could produce perfectly acceptable results by simply 
making sure I started with a clean brush or palette knife.</p>
