Color

Let L(l,i,e,g) be the total reflected light.

l wavelength

i angle of incident light

e angle of emitted light

g phase angle

• The surface reflection component L (l,i,e,g) appears

as a highlight or gloss.

• The body reflection component L (l,i,e,g) gives the

characteristic object color.

Then L(l,i,e,g) = L (l,i,e,g) + L (l,i,e,g)
