Info: The BSDF acronym means Bidirectional Scattering Distribution

Function, which identifies the mathematical function that controls how a

surface scatter light.

If you have to create materials with only a simple color, add the Diffuse

BSDF as a shader. That shader has a color picker, and you will be able

to get the color you want and use it for any selected 3D object (Figure

5.4).

Notice how each field in the material options has a colored circle on the

left side. Those circles and colors identify the type of data you can use

for each field. A green circle means a shader, and a yellow one means
