Use the same color picker (you can find some free color picker on the web) for both software. (I do not use Photoshop, so I can not help you much)
Also, use safe color (it 's simplier and you are pretty use to get the same color)
Try not to use color background, you 'd better use transparency (no color) as the same problem will appear in your web page (background HTML different that Flash background or picture bg).
You can modify in the HTML file the background color of your Flash object (in the object tag). This could help also.
