Description Alex 2017-09-19 08:10:43 UTC 
This feature is useful for wide gamut and color-calibrated displays. GNOME Desktop provides color management out-of-the-box, but currently Epiphany doesn't seem to take advantage of it.

This feature is available in:
- Firefox (needs to be enabled in config)
- Chrome
- Safari
- IE

When Image is untagged (doesn't have color profile embedded browser assumes that it's sRGB. Also all css color definitions are assumed to be sRGB (Firefox default) so are displayed correctly on color-managed and wide gamut displays.

Under Firefox this feature has got some options:

...but only gfx.color_management.rendering_intent is important. For display (not print) work it can be safely assumed, that "perceptual" intent is used so no new options have to be added to UI.

Again, this is way below Epiphany level. Color management has to be implemented in WebKit. I'm sure the cross-platform bits are already there, because Apple cares about color management, but I have no clue what the state of Linux-specific support is.

Thanks for taking the time to report this.
