To revisit the properties of cool and warm temperatures, we look at using 6 warm or 6 cool colors in a drawing that will be of a white object. First, create a blended color scale, and below, a blended black/grey/white scale of corresponding values. Blended: one color or value into the next.
The above example uses only the blue colors.
The prismatic spectrum (the color wheel) is divided in half (the warm or cool half, also labeled on the wheel). The six cool colors on the spectrum are: yellow-green, green, blue-green, blue, blue-violet and violet. Below are some basic instructions for the drawing. For the drawing exercise we choose either the warm or the cool palette. Use the cooler values in each 6 color section (closer to blue) for cast shadows, and darker values on the object, and warmer hues for the lighter areas that are cast in light. Color temperature is always relative, and changeable. So that a green, for example, may be cool in one situation, but warm in another.
I like to use wooden toys that have been spray painting white, as well as small bird houses, as seen in the first example above. Below are examples of drawing from a wooded scorpion in the warm palette: red-violet, red, red-orange, orange, yellow-orange and yellow.
The example below just uses the warm colors:
Do you prefer the warm or cool palette?
