|
How conversions take place from one colour space to another
|

|
What is Perceptual Rendering?
|
Compresses all the colours until the out of gamut colours reach the closest re-producible hue in the destination space
|
|
|
What is Saturation Rendering?

A bad idea
Saturates hues at the expense of colour accuracy. DON'T DO IT |
|
|
What is Relative Colourmetric Rendering?
|
Takes the out of gamut colour and compresses them to the closest available hue in the destination
|
|
|
What is Absolute Colourmetric Rendering?
|
Attempts to match LAB values (coordinates) of the destination with the source but DOES NOT adjust for different white media white points
