Coffee roasting is done in different ways. Some stop roast when the beans has reach a certain color.
You can hear about this in my podcast Coffee Roasting Navigated. Episode 3 is about roasting to a certain color. We are at a roasting course with Morten Münchow from CoffeeMind. I have called the episode “Roasting by color”, but Morten focuses on more than the bean color to make a good roast.
In Episode 7 roaster Kaya Caretta tell about looking at the color during the roast. Listen at http://coffeenavigated.net/podcast/episode-7/
