Jetpack Image Optimizer Ruins Colors (RGB vs sRGB Compression)
-
Hey guys.
I am talking of this setting in particular; Speed up image load times
Issue is chronic to Jetpack for what I can tell, I am using
Jetpack 8.8.1
Firefox 79.0 (latest version)
Wordpress 5.4.2Colors when the setting is turned OFF:
Colors when the setting is turned ON:
The image above is RGB, not sRGB but Firefox processes it “correctly”, meaning that it shows it with the same degree of saturation it had when I worked with it on Photoshop CS5
Here’s a link to all the information of the image itself:
This is a direct link to the image:

This issue happens only when using WordPress Carousel, and only when the setting above is enabled. The website thumbnails are shown on their correct colors, be them on tiled mosaic, circles, square tiles, tiled columns, default wordpress galleries or slideshows. they of course will appear in a lower resolution, but the colors are correct. So that means that Jetpack compression is somehow not affecting the colors of the Thumbnail compressed images, but it is screwing up the colors for the bigger Carousel images.
The problem appears to be that the compression system that you guys are using is forcing Firefox to load the images as the “wrong” version, which is just overall strange unexpected and inconsistent behaviour, given that when disabled Firefox handles the images flawlessly

Oh, id worry more for the poor soul that will need to go digging what’s causing this issue in particular than getting credit, handling RGB vs sRGB is quite the horror show afaik
Anyhow, I did as you asked me James, thanks for letting me know of the github page, that will make things far easier. I tried to go around searching and could only find this forum not the official github! Even iirc the website they used only links to itself with dead outlinks, they really ought to fix that one up asap
Anyhow, regards James, and given that I already posted there I’ll fill this support thread as resolved
