The color of certain images is displayed incorrectly (PNG images it would seem)

This is not a graphics card issue or color profiles. the images look fine in chrome and other browsers, and in photoshop. Firefox is displaying colors from PNG files incorrectly.

By default, Firefox will try to color manage JPEGs and PNGs tagged with a color space but not others. You can review and experiment with the following preferences to see whether one of them improves the rendering:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful.

(2) In the search box above the list, type or paste gfx.c and pause while the list is filtered

gfx.color_management.mode - governs application of color management to images

  • 0 = off
  • 1 = on for ALL images
  • 2 = on for TAGGED images (default)

I can't recall whether you need to exit/restart Firefox before changes to this preference, or changes to the below preferences, takes effect.

gfx.color_management.display_profile - if you have created a custom monitor profile and Firefox is not using it, you can enter the path to it here.

gfx.color_management.enablev4 - double-click to toggle to true if your custom monitor profile is an ICC v4 profile

gfx.color_management.rendering_intent - whether Firefox honors or overrides the intent flag in the ICC profile, by default, overrides to Perceptual

Can you find a combination of settings that gives you the colors you expect?
