| 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. |

| Permissible Value(s) | Value | Value Meaning |
| | CIE_XYZ | Tristimulus values defined by CIE. |
| | CIE_xyY | Chromaticity and luminance coordinates defined by CIE. |
| | HSI | Hue, Saturation, Intensity |
| | iRGB | Instrument RGB. This is Red, Green, Blue color as it comes from the instrument, without any color correction. |
| | pRGB | Planetary 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. |
| | sRGB | Standard RGB, as defined by XXXXX. Corrected Red, Green, Blue color using a standard 5000K illuminant. |
| | wRGB | White Balanced RGB. Red, Green, Blue with a simple white balance applied. |
