| Unsupported | 0 | Unsupported Color Space |
| Transparent | 0 | No color; transparent |
| DeviceGray | 1 | Black, white, and intermediate shades of gray are special cases of full color. |
| DeviceRGB | 2 | Colors in the DeviceRGB color space are specified according to the additive RGB (red-green-blue) color model, in which color values are defined by three components representing the intensities of the additive primary colorants red, green, and blue. |
| DeviceCMYK | 3 | The DeviceCMYK color space allows colors to be specified according to the subtractive CMYK (cyan-magenta-yellow-black) model typical of printers and other paper-based output devices. |
| CalGray | 4 | A CalGray color space (PDF 1.1) is a special case of a single-component CIEbased color space, known as a CIE-based A color space. |
| CalRGB | 5 | A CalRGB color space is a CIE-based ABC color space with only one transformation stage instead of two. |
| Lab | 6 | A Lab color space is a CIE-based ABC color space with two transformation stages. |
| ICCBased | 7 | ICCBased color spaces are based on a cross-platform color profile as defined by the International Color Consortium (ICC). |
| Separation | 8 | A Separation color space provides a means for specifying the use of additional colorants or for isolating the control of individual color components of a device color space for a subtractive device. |
| DeviceN | 9 | DeviceN color spaces can contain an arbitrary number of color components. |
| Indexed | 10 | An Indexed color space allows a PDF content stream to use small integers as indices into a color map or color table of arbitrary colors in some other space. |
| Pattern | 11 | A Pattern color space enables a PDF content stream to paint an area with a pattern rather than a single color. |
