Also to know is, can you color in blender?
The color can be chosen. Use the color that can be set per object in the Viewport Display Object panel. Use the color that can be set per material in the Viewport Display Material panel. A random color will be selected for every object in the scene.
Also question is, what is the vertex coloring of a graph?
Vertex coloring is an assignment of colors to the vertices of a graph ‘G’ such that no two adjacent vertices have the same color. Simply put, no two vertices of an edge should be of the same color.
What is Vertex Alpha?
From Valve Developer Community. $vertexalpha and $vertexcolor are two VMT commands that make the surface derive its alpha and color values from per-vertex data provided by the engine.
Applying vertex colors is a great way to colorize levels for prototyping, team layout, zones, and more. You can apply unique vertex colors to faces or objects in order to easily identify where they begin and end. You can also apply vertex colors to vertices and edges for visual effects.
Vertex color, or vcolor, is just a color with RGB and alpha channel values stored for each vertex of a mesh. Vertex color and alpha can be used for multi-texturing, transparency, or fake ambient occlusion. Vertex color is typically multiplied against the Diffuse color, colorizing or darkening the color map.
