Editing Colorfulness (section)

=== CIECAM02 ===

In [[CIECAM02]], saturation equals the square root of the ''colorfulness'' divided by the ''brightness'':
<math display=block>s = \sqrt\frac{M}{Q}</math>

This definition is inspired by experimental work done with the intention of remedying [[CIECAM97s]]'s poor performance.<ref name=ciecam02>{{cite conference|conference=The CIECAM02 Color Appearance Model|title=IS&T/SID Tenth Color Imaging Conference|last=Moroney|first=Nathan|author2=Fairchild, Mark D. |author3=Hunt, Robert W.G. |author4=Li, Changjun |author5=Luo, M.
