Bug Description

Ubuntu version 18.04.5 LTS.

gnome-screenshot:
  Installed: 3.25.0-0ubuntu2
  Candidate: 3.25.0-0ubuntu2
  Version table:
 *** 3.25.0-0ubuntu2 500
        500 http://archive.ubuntu.com/ubuntu bionic/main amd64 Packages
        100 /var/lib/dpkg/status

Expected: Both colors on the image and the web page are the same hex code.
Happened instead: Diffent colour hex.

Taking a screenshot from a webpage changes the colors slighlty.

I have attached a video of what is happening, its a slighlt different colour but still different altogether.

From a HTML page it is #11283C but when I place the screenshot on top of a background with that color, its clearly different.
On image the hex is #0D253D.

I have attached a video of the process
