CLF color by slope automatically assigns the color of the slope according to the slope of the surface. By default, the steeper the slope, the brighter the color, and the slower the slope, the grayer the color. You can customize the color displayed by different slopes, which is very convenient for auxiliary terrain and scheme analysis.
