Color Gamut refers to the range of colors a device, such as a projector, can produce. Gamut readings are represented as a triangle or a color space on test results. The standard for color gamut in the projection industry is the Rec.709 standard.
Some projectors support a color gamut wider than the Rec.709 standard, like Rec.2020/BT.2020. Color Gamut can be affected by various factors such as the projector's light source, color wheel, or laser phosphors, as well as the projector's settings and the ambient light.
