There
are good reasons why yellow is so difficult and complex:
yellow has the flattest dark-light value potential and the
lowest saturation potential of any hue. Pure yellows are
very sensitive to shading or tinting; in fact, “uptight”
would probably be the better word. High yellow hues are
unforgiving. Their reaction to even the smallest addition
of other shades of yellow is generally frantic. This meant
that I had to keep calm, especially since my technique requires
so much work in detail. Any mistake in shading would immediately
stand out as an optical rupture in otherwise finely sequenced
color gradients. The real challenge is to paint color fields
that are very lively, vibrant, and tense nevertheless.
