The addition of the suffix "-ation" to the word "color" (American English spelling) or "colour" (British English spelling) results in the spelling "saturation".

Colour saturation refers to the intensity or purity of a specific colour in an image or visual representation. It is a measure of how pure and vibrant a colour appears, without the presence of any added white, grey, or black. In other words, it is a measure of the strength of the colour's hue.
The saturation of a colour is determined by the amount of pigmentation or chroma it possesses. A highly saturated colour appears vivid, rich, and vibrant, while a desaturated or low-saturation colour appears dull or muted. Saturation is one of the three dimensions that define a colour in the HSL (Hue, Saturation, Lightness) or the RGB (Red, Green, Blue) colour models.
In terms of image editing or graphic design, colour saturation can be adjusted to enhance or modify the overall appearance of an image. By increasing or decreasing saturation, one can manipulate the intensity and vibrancy of colours to achieve a desired effect. For example, increasing the saturation can make colours pop and appear more vibrant, while reducing saturation can create a more subtle and muted look.
Colour saturation is often used to evoke specific emotions or moods in visual compositions. Highly saturated colours are associated with energy, excitement, and passion, while desaturated or low-saturation colours are often linked to calmness, tranquility, or seriousness. Understanding and controlling colour saturation is an essential skill for photographers, artists, designers, and anyone working with visuals to effectively convey their intended message or aesthetics.
