Need RGB from Appearance Color

The color property in the AppearanceSettings can be set using the RGB values like this:

color_value = MAX(MIN(red_rgb_value,255),0) + MAX(MIN(green_rgb_value,255),0)*16*16 + MAX(MIN(blue_rgb_value,255),0)*16*16*16*16

Ref: http://help.solidworks.com/2017/english/api/sldworksapi/SolidWorks.Interop.sldworks~SolidWorks.Interop.sldworks.IAppearanceSetting~Color.html

The component uses an appearance file 'satin finish aluminum.p2m' (attached)

The dominant color of this component is

Using the above equation the color value should be = 16733263

I use swModelDocExt.get_DisplayStateSpecMaterialPropertyValues() using swDisplayStateOpts_e.swThisDisplayState for DisplayStateSetting to get the AppearanceSetting.  But, the color value returned is 15592165

Why is it different? Can someone please explain.

How can I get the RGB value of the Dominant color from the appearance color integer value?

( I need RGB[79, 84, 255] from Appearance Color integer 15592165 )
