[Electronics-talk] [EXTERNAL] Color Identification Technology

Sat Dec 19 13:05:23 UTC 2015

I've seen the color identifier you mentioned before, Andy.  I knew a guy 
that had one and he used it to see if a page was blank.
It also would tell you the color spectrum, I believe.  Like, it would tell 
you how much red and blue and the such were in the color.
The one thing I thought was weird about it was the bingo calling feature. 
There was no way to review the winning numbers.
This same identifier said that I was vivid chocolate when I put it on my 
skin.  I've never heard of vivid chocolate until then.
