NonsRGB

NonsRGB is a term used to describe display color spaces that do not conform to the sRGB standard. The sRGB (standard Red Green Blue) color space was developed by Hewlett-Packard and Microsoft in 1996 and is widely used as a default for digital images and displays. It defines a set of primary colors, white point, and gamma curve.

Displays that are "nonsRGB" may exhibit colors differently than expected when viewed on an sRGB-compliant display, or vice versa. This can occur due to various reasons, including the use of different display technologies, custom color profiles, or intentional design choices for specific applications. For example, professional photography and graphic design often utilize wider color gamuts like Adobe RGB or DCI-P3, which encompass a larger range of colors than sRGB. These wider gamuts are considered nonsRGB.

The mismatch between a nonsRGB display and an sRGB environment can lead to color inaccuracies. Colors that appear vibrant and rich on a wide-gamut display might look washed out or oversaturated when viewed on a standard sRGB monitor. Conversely, colors intended for sRGB may appear dull on a display with a significantly larger color space if not properly managed. Color management systems are employed to bridge these differences, allowing for more consistent color reproduction across various devices and color spaces. Understanding whether a display is sRGB or nonsRGB is crucial for professionals who rely on accurate color representation.
