In which temperature group does orange formed by mixing yellow and red generally belong?

Correct answer: Warm colour

The governing concepts are colour mixing and temperature classification. In traditional pigment mixing, yellow combined with red produces orange. Because both yellow and red are generally classified as warm colours, orange is also usually placed in the warm group. Blue and green are common cool examples, while neutral colours are greys, blacks or whites; orange is neither neutral nor colourless. Its exact warmth can vary with the mixture, but its usual classification remains warm.
