Figure 1 shows the measured Color Gamut for the Surface 3 along with the Standard sRGB / Rec.709 Color Gamut in black. The outermost white curve is the limits of human color vision - the horseshoe is the pure spectral colors and the diagonal is the Line of Purples. A given display can only reproduce the colors that lie inside of the triangle formed by its primary colors. Highly saturated colors seldom occur in nature so the colors that are outside of the Standard Gamut are seldom needed and are unlikely to be noticed or missed in the overwhelming majority of real images. Note that consumer content does not include colors outside of the Standard Gamut, so a display with a wider Color Gamut cannot show colors that aren't in the original and will only produce inaccurate exaggerated on-screen colors.

The dots in the center are the measured color of White for the Surface 3 along with the D65 Standard White, which is marked as a white circle. To deliver accurate image colors for standard consumer photo, video, internet, computer, and HDTV content the display must match the Standard Color Gamut and the Standard Color of White.

The Color Gamut of the Surface 3 is slightly too large at 0 lux, which is absolute darkness, shown in blue below, but it is a very good match to the sRGB / Rec.709 Standard Gamut for 300 lux ambient light, which corresponds to typical workspace indoor ambient lighting.
