The Flat Appearance Type is not shaded, so it does not react to light or shadows. Therefore, the Flat appearance has a constant color regardless of lighting and shadows.
The Flat appearance is unrealistic and suited for tasks such as masking. A mask is an area that you can protect and isolate from changes you apply to the rest of the image.
