What is the range of the SRM scale for beer color?

The SRM scale ranges from 1 to 60, going from extremely pale to black. However, this scale cannot be accurately represented graphically because a picture of a colour does not account for transparency or density, which affects the amount of light lost to the beer.

What is ASBC color?

The ASBC Beer Color scale has a range of approximately 1 to 11 units, with the more yellow, pale worts at the low end of the scale and the redder color of dark worts, beers and caramels at the upper end of the scale. The industry reference method for ASBC Beer Color and Turbidity Is: ASBC Beer-10 Color of Beer Part A.
