Re: TCS3200 anyone?

I would question the colour option. I'm not sure how reliable it would be. 

Density or some form of sound measuring device may be more accurate.  A nut
may be the right colour but have a hole in it which makes it unsuitable. Tree
are now graded by sound reflections before they are even cut to determine
their grade. Maybe something along these lines would be better.
