Very good observation indeed, Pankaj. Coming back to the color & other specifications of herbarium sheet. While at FRLHT, I had chance to digitize few thousand herbarium specimens from various sources. The ivory or white sheets gave better results with even and clear background (this is important to have undisturbed viewing of specimen details, even when zoomed in), whereas, the even slightly dull or greyish sheets produced bad images. editing was cumbersome and when tried to brighten, the specimen image used to get bleached thus loosing its details.
When buying handmade paper, we should also avoid the ones with too many visible fibers on the surface, they may be in different colors. So, it is preferred that at least one side of the sheet should be clean white with smooth finish. The size may be between 300 to 500 GSM (needs verification) so that it doesn't bend when woody specimens mounted on them.
