title: Video appears to be of different colour on different OS/screens
body: <p>I have a <code>video.mp4</code> which has a purple background colour. I want to place this video on my webpage, with the same purple background, so that the video looks like part of it.</p>
  <p>On a website, I have the same purple background, and the video should blend in. However, on different screens, it appears as a slightly different shade of purple. Is it possible to re-encode the video to be consistent across all screens?</p>
  <p>I do not have access to the source file, only to the <code>video.mp4</code>.</p>
  <p>After searching, I <a href="https://video.stackexchange.com/questions/32075/yuv-to-rgb-srgb-color-space-conversion-using-ffmpeg">found this answer</a>, however, it produces a 'broken' video.</p>
