Adjusting colour of new misc ingredient

I have added Rooibos tea as a misc item to my Beersmith, but there is no option for the colour value of the rooibos, which is quite red and will have a large impact on the colour of the finished beer.
Is this possible or has it been done already?
Thanks

Hi,
  By default the Misc items don't affect color.  If you want to add color it would have to be a "grain" or fermentable item, and you can add the estimated color field there.
