Colored pencil on paper, 6.5" x 10"
The colors we know can be divided into two groups - warm colors and co0l colors. We can place a dividing line on the color wheel between yellow and violet to identify these two groups.
We generally associate red, orange and yellow hues with the sun or fire, and call them warm colors. We also associate blue, blue-green, green, and violet hues with water, sky and atmospheric conditions, and call them cool colors. However, the perceived qualities of warmth or coolness in a color can be influenced by other colors near it.
In this drawing, I used twelve separate pencil colors, six highly-saturated colors from the color wheel, two browns and four paler tones of yellows and pinks.
