When I worked at UCD Veterinary Pathology Dept. I built a transilluminator box using colored plastic sheets with a light backlight with a reostat control. I used a lightly frosted glass ( as a light defuser to eliminate hot spots and place the specimen on) to produce colored background of various intensity an well as with cheezecloth cover over side floodlights to take pathaological specimen photos without shadows to be published of experiment results by Professors and PHD theses candidates in medical journals. Have fun !
