This is one thing where you may be fighting a loosing battle in which I've struggled most my digital era age. One of my clients for example, prefers that I clip out the backgrounds of my product shots so they can then put the tiff file of the clipped subject in just about any application such as web, catalogs, flyers, magazine, etc without having to fuss with the background. That's fine but their internet's background color is white. The problem being once I throw in a white subject or a clear or even natural color subject in that white background, While they may look good on my color calibrated screen, a manager who may have their crappy late 90's monitor next to a large window, and poor calibration, the objects can then get lost within their white backgrounded website. You can darken the edges, but then you get complaints that it looks too illustrative with hard edge lines... You could make the whole thing darker or less contrasty and then it may look great on their screen but look hideous to modern monitors. You can see how this can get very dicey, especially when dealing with their clients who may be that 70-80 year old chairman in that corner office with a bad monitor. The irony is they always praise my print work such as catalogs, flyers, banners, etc and say that want that quality on the web, but they cant figure it out that they are getting that quality, but if they tried looking at my print files on their bad monitors/set-up, it will look like crap. I've learned to slightly reduce contrast to bring in more mid tones for bad monitors and dont let it get to me because there is almost nothing you can do about it other than have some disclaimer on the site saying that colors may vary depending on monitor calibration and maybe even have a link or two to colorrite or mcbeth monitor calibrators.
