 * Xviewer version (xviewer --version): 3.4.4
 * Distribution - (Mint 17.2, Arch, Fedora 25, etc...): Linux Mint 21.3 Cinnamon

Issue

Colors displayed are slightly muted from expected colors, tested with a color picker on a color I know to be #F0758A is read as #D57889 instead

Steps to reproduce

  1. Open file explorer
  2. Have image previews active with largest size/closest zoom
  3. Open one image with Xviewer
  4. Open color picker application
  5. Pick a color on the image in Xviewer
  6. Pick the same color on the image in file explorer

Expected behaviour

Colors should match between file explorer preview and Xviewer

I have just taken a screen-shot of the above image, saved it to the clipboard and pasted it as a new image in GIMP (V2.10.36). I get the same values that you note above for the pink hair - 0xf0758a on the left and 0xd57889 on the right.

I get exactly the same values if I use the right-click context menu in Firefox to save the image and then open it in GIMP.

Furthermore I gt exactly the same values if I set nemo to show large icons, take a screen-shot of the icon, copy it to the clipboard and paste it into GIMP as a new image.

Could you have an issue with colour profiles - for instance is there one set for your monitor?

Problem is I have Linux Mint installed on my Alienware X17 laptop, and while the color management app recognizes the display type, it won't allow me to adjust it. However, the fact that the colors are displayed correctly everywhere except Xviewer, leads me to believe the issue is within Xviewer itself.

What I missed from my previous post is that I opened the saved image in xviewer, saved a screen-shot to the clipboard and pasted this as a new image in GIMP - the values were exactly the same.

I don't seem to be seeing the issue.

That is really odd, I could try to reinstall Xviewer and see if it's a bug in the code on install, I'll update when I get to it.

I've attempted to reinstall Xviewer, and the issue still persisted, I also decided to use my other laptop that I also have Linux Mint installed on to test Xviewer there, and it's working perfectly fine, all the colors match. I'm going to assume there is an issue with color profiles on my laptop then, so I'll send the system info to see if there is an issue with any of the hardware/software from it

Quick update: I just used an alternative image viewer I didn't know I had, that being Pix, and I quickly found I was having the same issue there as on Xviewer, and after a look at the buttons I had available, I disabled "Apply the embedded color profile", to see it look the exact same as the file preview. So now that I know what the issue actually is, how do I disable the applied embedded color profile on Xviewer?
