VertexColors

✖
`VertexColors`

✖

is an option for graphics primitives which specifies the colors to assign to vertices.

Details

VertexColors can be used with Polygon, Line, Tube, Point, and GraphicsComplex.
VertexColors->{col₁,col₂,…} specifies that color col_i should be assigned to vertex i.
The interior of the polygon is colored by interpolating between the colors specified by VertexColors.
In 3D, settings for VertexColors can include any surface or material property, to be used with simulated lighting.
The colors col_i for each vertex can be an explicit color directive such as GrayLevel[g] or RGBColor[r,g,b], or can have the following forms:
g GrayLevel[g]

{g,a} GrayLevel[g,a]

{r,g,b} RGBColor[r,g,b]

{r,g,b,a} RGBColor[r,g,b,a]
