What may the first colour in a tertiary colour name indicate?

Correct answer: The dominant bias of the mixture

The governing concept is descriptive colour naming. In a name such as red-orange, the first colour can indicate the mixture’s dominant bias or the hue toward which it appears to lean. This helps the artist understand the visual character of the sample, although the exact appearance also depends on proportions and materials. Paper colour, brush size, and price do not determine the name’s first part.
