public static float calculateFinalLumValue(Double tint,
                                           float lum)

If tint is supplied, then it is applied to the value of the color to determine the final color applied.

The tint value is stored as a double from -1.0 .. 1.0, where -1.0 means 100% darken and 1.0 means 100% lighten. Also, 0.0 means no change.

In loading the value, it is converted to HLS where HLS values are (0..HLSMAX), where HLSMAX is currently 255.
