- The wide-gamut RGB color space (or Adobe Wide Gamut RGB) is an RGB color space developed by Adobe Systems, that offers a large gamut by using pure spectral primary colors.It is able to store a wider range of color values than sRGB or Adobe RGB color spaces. As a comparison, the wide-gamut RGB color space encompasses 77.6% of the visible colors specified by the CIELAB color space, while the standard Adobe RGB color space covers just 52.1% and sRGB covers only 35.9%. When working in color spaces with such a large gamut, it is recommended to work in 16-bit per channel color depth to avoid posterization effects. This will occur more frequently in 8-bit per channel modes as the gradient steps are much larger. As with sRGB, the color component values in wide-gamut RGB are not proportional to the luminances. Similar to Adobe RGB, a gamma of 2.2 is assumed, without the linear segment near zero that is present in sRGB. The precise gamma value is 563/256, or 2.19921875. The white point corresponds to D50.The chromaticities of the primary colors and the white point are as follows: (en)
- 寬色域RGB色彩空間（或稱Adobe寬色域RGB色彩空間）是一個由Adobe所開發的能夠提供一個使用純光譜原色混合構成的寬汎色域。該色彩空間包含CIE LAB色彩空間中指定的可見色彩的77.6%，相較的52.1%來説提升明顯。 由於該色彩空間十分巨大，所以一般建議採用16位色深工作模式以防止出現過於明顯的色調分離現象。在通常的8位色深工作模式中該問題會非常顯著，因爲在該模式下色彩的梯度會非常大而且明顯。 與sRGB類似，寬色域RGB中的色彩分量值和亮度并不成正比。其伽馬值為與Adobe RGB同樣均爲563/256（約爲2.2），并且白點對應為D50。 (zh)
