I'm having problems uploading a png file to the web. The problem is that it distorts the color of the image. The image is a trademark and uses a PANTONE color. I think this could be the problem because the distortion affects only this color alone.
I have tried saving it for normally, for web, in multiple formats (jpg, png, gif) Always the same exact result: color distortion.
So, how can I upload this image without having to change the color?
EDIT: Here's a link to the image because I don't have enough rep to publish any image yet:
EDIT 2: OK, it seems that the problem is Facebook, which is the place I'm trying to upload this trademark, because I uploaded this to ImageShack and it shows correctly.
Any advise on how to fix it?
