Lab Color space vs RGB
Is it true that Lab color space is larger than RGB color space? For example, there exists a color in Lab that can't be reproduced in RGB space ( outside of monitor's gamut)? How does the function rgb2lab deal with this case? From the code, I saw that there's always a corresponding mapping one to one between Lab and RGB.
A follow up questions is: Which rendering intent is used when converting from XYZ to RGB? (AbsoluteColorimetric, Perceptual, RelativeColorimetric or Saturation). The formula is presented in this link, but I couldn't interpret it. http://www.easyrgb.com/index.php?X=MATH&H=01#text1 On Saturday, March 28, 2015 at 10:37:13 PM UTC-5, Dzung Nguyen wrote:
