 The color displayed as a function of their input value can be determined with the following formula, where $S$ and $B$ are the saturation and brightness settings respectively. Figure \ref{fig:HueLightPanelColor} shows an example of the resulting colors for inputs in the range $[-1, 1]$ with $\text{saturation} = \text{brightness} = 1$. Inputs smaller than $-1$ result in the $[-1, 0]$ range being repeated, while inputs greater than $1$ result in the $[0, 1]$ range being repeated.
