The TIFF standard is here:

http://partners.adobe.com/public/developer/en/tiff/TIFF6.pdf

The description of palette images is in section 5. For palette images, the number of bits per sample can be 4 or 8, corresponding to 16 or 256 colors (the color values are short integers, however, giving 65536 levels for each of red, blue and green at each index). For more colors than that, you must go to one of the RGB full color modes.
