I have mixed feelings with color cards. They might be helpful for a
beginner but they might also add confusion if because they are a
beginner they don't understand that some beans will tend to color
differently and at different times. It's also important to understand
the relationship between surface color and ground or inner color. I
suppose it could be used to add the color numbers in a log record.
It could be quite helpful for us to use to communicate when discussing
a specific bean. It can help diagnose some roast issues. I find I'm
most interested in the 2 Agtron readings when checking out Ken Davids
