is a three-dimensional graphics directive specifying that surfaces that follow are to be drawn with a warm color facing toward the light and a cool color facing away.


uses cool and warm colors obtained by blending col with slate Blue and Orange.


uses the cool color ccol and the warm color wcol.


uses the colors ccol and wcol weighted by the wi.


uses the specified gradient color scheme in ColorData.


  • GoochShading is also known as cool to warm shading.
  • GoochShading is typically used to highlight details and contours of three-dimensional objects.
  • The final colors of 3D surfaces are determined by linearly adding RGB colors from the diffuse reflection, specular reflection lights.
  • GoochShading[{w1,w2}{ccol,wcol}] specifies that luminosity on the surface should be mapped to the color gradients between ccol and wcol weighted by w1 and w2. A higher weight wi indicates that more of the corresponding color should be used.
  • Colors can be defined by RGBColor, Hue or any other color specification. Any number of colors can be used.
  • GoochShading[] is effectively equivalent to GoochShading[{LABColor[{0.4,0.4,-0.7}],LABColor[{0.7,0.5,0.8}]}].
  • In GoochShading[{ccol,wcol}], the colors ccol and wcol are weighted uniformly.
  • The setting Lighting"Accent" uses a directional light and faithfully reproduces colors on the surface.
