Personality Editor Color Mixing Options

Question

I am editing a Pluto2000XE RGBW Zoom Wash. The drop down options in the Personality Editor have RGIW, and I assume the letters stand for Red Green Intensity White ? I cannot see RGBW, can someone please explain the discrepancy, thanks.

It stands for Red, Green, Indigo, White. 
 It's still controlled as RGBW but uses a deeper blue for the color picker calculations than the 'classic' RGBW. These days most RGBW/RGBA/RGBL LED fixtures are actually using an 'indigo' rather than a classic 'blue' LED>
