Colorshift: Difference Brown|Green - *.jpg and *.png with Firefox Browser in NMB

[Kunehito]

Hi internet experts,

 

just realized: if I post a picture as .jpg file - on my desktop the colors look ok - if I upload them they got a greenish effect.

 

This does not occur when I upload them as .png. Using Firefox as a browser.

 

Made a screenshot of it. right: *.png with intened color - brownish / left: uploaded as *.jpg greenish tint

 

any Idea if this can be fixed? anyone else got this issue?

Cheers,

Tobi

I'm a bit colour blind...especailly between green and brown, so I'm the wrong one to ask. The forum software doesn't use any real image processing aside from the standard php plugins for resizing. If the images are too large, it will downscale them automatically. Nothing is done to the colour, but maybe there is some reaction while doing the processing. Nothing I can control, it's external functions done by the hosting, same as any website that uses the same image handling processes.

You could well have a color space issue - if the information isn't in the image the browser assumes a color space and other tools make different guesses.  How are you generating the images?

Thanks  Brian and Richard!

 

I am using Affinity publisher on a Windows PC as a tool. By sending the information via export to png or jpg. OFC there are several choices to select different color spaces.

 

Never touched these hidden settings so far. I will make some trials and let you guys know about the outcome. Sounds promising.

 

Best,
