Defines how per-feature colors set from the Cesium API or declarative styling blend with the source colors from the original feature, e.g. glTF material or per-point color in the tile.

When REPLACE or MIX are used and the source color is a glTF material, the technique must assign the _3DTILESDIFFUSE semantic to the diffuse color parameter. Otherwise only HIGHLIGHT is supported.

A feature whose color evaluates to white (1.0, 1.0, 1.0) is always rendered without color blending, regardless of the tileset's color blend mode.
