Gradation is a color progression used in displays to indicate gradual changes in the intensity of color tones.
Gradation, in its simplest form, is the transition from one color tint or shade to another, from lightest to darkest. Poor gradation can only express a certain number of colors, which can lead to aliasing on the image and a lack of accurate color reproduction. On the other hand, numerous gradation expressions can replicate visuals that are more realistic.
Gradation in the display industry refers to the linear orderly progression of colors using variations in luminance.
Simply put, it describes the gradual transition of color expressions from the lightest to the darkest.
A display can represent richer and more detailed colors if the gradation spectrum contains a greater number of colours.
