Conversion method

Recommended

RGB

Any other color space.

Built-in, ICC profiles, or emulation tables, depending on the destination color space.

 

BGR

Any other color space.

Built-in, ICC profiles, or emulation tables, depending on the destination color conversion.

 

YUV

Any other color space.

Built in.

 

CMYK

Any other color space.

1.Emulation Tables (one way CMYK => RGB)

2.ICC Profiles.

3.Built in.

The best conversion is through the ICC Profiles (USE_ICC), this is because of the nature of the CMYK conversion, which is machine-dependant. You can use profiles that vary in the degree of black color (ink) generation.

HSV

Any other color space.

Built in.

 

HSL

Any other color space.

Built in.

 

YIQ

Any other color space.

Built in.

 

CMYK

1.Built in.

2.ICC Profiles

 

LAB

Any other color space.

1. Emulation Tables (one way CMYK => RGB).

2. ICC Profiles.

3. Built in.

For two-way conversion, RGB to LAB and vice versa, the best solution is with emulation tables and Built in conversions, because the colors are preserved better. However for one way you can use ICC profiles.

XYZ
