Ah I see, thank you, I will take a look at this !!!

Thank you for your reply Alan, but the problem is that the image shown in the picturebox is edited by the user. When the user save the file it must be the same as shown in the picturebox.

Even, when the image is shown in the picturebox, and I do a windows printscreen and paste the result in paintnet, then the result shown in paintnet is also less saturated. So there is something "going on" in the picturebox.

Perhaps I was not clear in what I asked. The problem is that the same bitmap shown in the picturebox is more saturated then shown in the Windows Photo Viewer.
