Definition: Each vertex in a mesh can optionally store an RGBA color value, called vertex color. These can be used for a variety of interesting and novel effects and/or shader inputs.
Common Usage: Vertex color is typically multiplied against the Diffuse Color, colorizing/darkening the color map.
Vertex color can be used for other purposes, like controlling blends between different texture sets, providing per-vertex sound effects in response to collisions, etc. When used for non-color effects, typically each color channel is treated as a separate monochrome set of values, so RGB vertex color can control three different per-vertex effects.
Depending on the game engine and mesh format, a vertex can be assigned multiple vertex colors. This duplicates the vertex, once for each color. This allows the color to change suddenly from one triangle to the next, creating a hard color edge.
Vertices can also store Vertex Alpha, typically for multitexturing, transparency, or Ambient Occlusion.
