### **Example: Coat Color**


The example below shows how the Coat Color affects the Diffuse, Reflection and Specular layers. The Diffuse color is set to light red and the Reflection color is white. In the first render, the coat layer is disabled. In the second render the Coat Color is the default white, and in the third one - yellow.



The image sliders show the respective render channels with the Coat Color set to default white and yellow. Notice how the specular highlights remain white regardless of the coat color.
