The fruit you hold now has the color orange , hence the name of the fruit.
It will best let itself describe in warmth.
Surfaces which are metallic and cold are usually reflective (light completely bounces off) or completely absorb the light rays.
This effects in the darkness you are unfortunately quite familiar with.
However , light has another feature. Light comes from the sun and also produces various grades of heat.
The orange is like the heat of a flame , absorbing little lightpower and giving the fruit its special color.
To put it in a little perspective : When comparing the color orange with other colors ; Think of the orange color as an almost touchable slow flame , the soft spot of the flame.
