Morphology
desaturation = desaturate (semi-transparent) = de + satur + ate + ion
This is a standard noun formation from the verb 'desaturate', meaning the process or event of desaturating.
Etymology
Desaturation comes from de- 'remove' and saturation 'full'. In medicine it means the blood is no longer 'full' of oxygen, so oxygen levels fall and monitors show a drop in saturation.
