color_space in Color_​Processing

Name: color_spaceVersion Id:
Description: Defines the color space in which this product is expressed. Some color spaces (e.g. XYZ or xyY) are independent of illuminant, while for others (e.g. sRGB or pRGB) the illuminant matters. It is expected that the defined color spaces will increase over time.

 iRGBInstrument RGB. This is Red, Green, Blue color as it comes from the instrument, without any color correction.
 pRGBPlanetary RGB. Corrected Red, Green, Blue color using an approximation of the actual illuminant at the planetary surface. For Mars missions this is typically 3000-4000K.
 sRGBStandard RGB, as defined by XXXXX. Corrected Red, Green, Blue color using a standard 5000K illuminant.
 wRGBWhite Balanced RGB. Red, Green, Blue with a simple white balance applied.
