Bounce lighting - reflective light.
Notes about color :
Bounce light a bit more saturated.
Mixte source light with local color by rolling the light a bit towards the light source on the spectrum.
If source and local color are from opposite side of the spectrum, the result will be more desaturated and darker.
The transition edge from a cast shadow or core shadow and lit area is usually more saturated.
