| As was described before the main idea of the Vibrancy is that the lowest saturated colors get the most relative boost in Saturation while highly saturated colors get progressively lower boost, up to a "no boost" for the 100% saturated colors. | As was described before the main idea of the Vibrancy is that the lowest saturated colors get the most relative boost in Saturation while highly saturated colors get progressively lower boost, up to a "no boost" for the 100% saturated colors. | ||
