title: Color rendering differents in Firefox and Chrome
body: <p>I want to capture screenshots of a website in different browsers and have assumptions about parts of the website having a specific color (I set it to red beforehand).</p>
  
  <p>However, when I compare the screenshots in Firefox and Chrome looking at them in an image application I can see that indeed, in Chrome the color of the element is #FF0000 whereas in Firefox it is #FC0D1B. </p>
  
  <p>I assume it has something to do with color profiles so I went to Firefox about:config and changed gfx.color_management.mode from 1 to 0. I tried every possible value but there was no difference.</p>
  
  <p>Can't I simply deactivate the color correction or somehow achieve the same result like in Chrome?</p>
  
  <p>It is very important for me that the element is actually #FF0000 because I look for elements with exactly that color with zero threshold.</p>
  
  <p>Here is a very simple jsfiddle where this also happens (only in Firefox).
  I just set <code>background-color:red</code> <a href="https://jsfiddle.net/don1savx/" rel="nofollow">https://jsfiddle.net/don1savx/</a> .</p>
  
  <p>I am using a Macbook Pro 13" 2013. My profile in Preferences -> Displays is set to Color LCD (at least I think this is what it's called in English)</p>
