Need a Visual Guide to Determine Coffee Roast Color?

Why not make your own coffee roast color guide?

Here are some images of “degree of roast” sets that I made. The boxes are a clear type used for displaying beads and other craft objects. I bought these from The Container Store as I recall.

The roast samples represent the degree of roast levels from green to Full City+. I skip some of the yellowing and browning stages, focusing on the levels starting just before First Crack, City Roast, City+, Full City Roast, and then a bit into Second Crack territory.

The set on the left dedicates one row to washed (wet-process) green coffee and the other to decaf, since decaf roast color can be so hard to gauge.

The set on the right also has wet-process coffee, compared alongside natural (dry-process) coffee. Each stage is the roast time and temperature equivalent. You can see how perceived color varies though.
