Unfortunately, in case of the Inovelli LED, the color is off. If I take the divide the value (221) in the driver code, the result is 61 and the color is more "turquoise" than blue. Hue = 65 seems to the correct shade of blue 
EDIT: I think RGB to HSL table in this link works for the colors (using [Hue X 100]/360)
