Colour is also affected buy your surroundings (colour of walls / light quality etc.). This can often have a massive impact on the colour people see. The most common example I find regularly is some B/W prints appear to have a colour cast through the printed result – simply take the print into outdoor natural light and this often changes the appearance dramatically.
A great way to see examples onscreen of this is at Dale Purve’s web site on colour (in our links page).
The best solution to this in your environment is to get a light viewing booth. These booths are calibrated to have the exact value of light at the viewing surface. This can not be easily done by simply changing your fluorescent light bulbs to daylight bulbs and painting your room a light neutral grey (although these is better than nothing).
