As a mixture
of red and yellow, orange absorbs some of the qualities of both
colours. It is brilliant and powerful when pure and since yellow
radiates light and red energy, it is very much by association
a colour of radiation.
When lighter
as in pale beige and darker as brown it has neutral warmth.
Orange is the colour of fire and of late afternoon sunlight.
It has association with festivity and celebration - but also
of heat and dryness.
Symbolically it can be changed with yellow
for the sun and red for heat.
