The Random Color Texture generates a random float value that creates color variations on geometry instances connected to a single material. Figure 1 shows a number of instances distributed using the Scatter on Surface node. A single Glossy material applies to all of the instances. Each instance has a random shade because the Random Color Texture node connects to the material's Diffuse channel.

Figure 1: Several instances of the same geometry have random shading after connecting a Random Color texture to the instance's Material

The Random Color Texture is useful when importing baked particle simulations that contain thousands of instances. It can create variations in the instance shading. There is just a single parameter - Random Seed. Changing this value shifts the random output of the texture.
