A series of beer glasses arranged in a row on a bar top, starting from the left with the lightest beer (2 SRM, pale straw) and transitioning smoothly to the darkest beer (40+ SRM, very black) on the right. Each glass should show a distinct color representing different SRM values. The colors should transition from light to dark, displaying the full range of the SRM scale. The setting is a warm, inviting bar with subtle lighting highlighting the gradient of beer colors from left to right.
