Hue differentiation:

Hue is the appearance of various specific colors, which is the main symbol to distinguish different colors and also the name of various colors, such as lemon yellow, rose red, sky blue, snow blue, etc.

So what determines the hue of an object? The hue of an object is determined by the composition of the wavelengths emitted by the light source and the properties of the object's surface. Of course, the reflectivity of the object's surface is also related to its color.
