What's the difference between colorWithSRGBRed vs colorWithDeviceRed vs colorWithCalibratedRed

Question

There are several convenience class methods for creating a NSColor. However, I can't seem to identify when to use the different class methods below:

colorWithSRGBRed:green:blue:alpha: vs colorWithDeviceRed:green:blue:alpha: vs colorWithCalibratedRed:green:blue:alpha:

Answer 1

tl;dr Use the calibrated colour space.

Rather than regurgitate the documentation - the answer is in the Color Programming Topics

Also the Color Space Overview

Edited to add

sRGB is one of the named Color Spaces.

Finally - and this is the last image from the documentation, and I hope it answers your question - if you want to use a color space, use the calibrated one.
