zoom in loosing saturation

Why do some photos in the search engine lose color saturation when those are enlarged (zoom in) and others don't?

Depends on the colour space they were uploaded in. Smaller sizes on the site and zoomed out previews show the smaller gamut sRGB version, which may look more saturated. A file uploaded in sRGB will look the same at all zoom levels. If a file was uploaded in the wider gamut Adobe RGB, they are converted to sRGB for the smaller sizes and so zoomed out versions show a more saturated sRGB version, but zooming in will show the original adobe profile, which may look less saturated.

Hm, but my photos are in sRGB and I see them desaturated when zoom in!?

That sounds odd - if you can post a file number I shall see what deal is. Certainly, what I wrote above is how the system used to work, it's possible a change could have been made.

ETA: the browser used can make a difference too, some having colour management turned on or off by default.

For example: File 22719331

First two steps of zoom the color is same but next two the color is desaturated.

Actually - scratch that. Thinking about it properly... sRGB files are converted to Adobe RGB for the larger sizes - and hence may look desaturated if you upload an sRGB file to start with. Please excuse the brain malfunction.

I always upload adobe rgb jpg for my illustrations but still the zoomed version looks 'greysh' and desaturated, why does it happen?

Any explanation on this? All steps of the zoom is the same. Here is what I mean, as soon as you zoom you can see the right colors, than they start changing (half and half on the first image on the left while loading) than, once the zoomed version is full loaded it becomes all desaturated. This both happens in firefox and ie which display the color preview differently from each other, but the zoomed in version is the same desaturated one for both. As I said previously, I upload an adobe rgb with embed ICC color profile jpg so there shouldn't be any further conversion as I understand happens for srgb files. I've checked other random illustrations from searches and only found this problem in a few of them, not all, however, all the ones from my port I've checked so far seem to be affected. Thanks
