2. The Standards of DCI-P3
For color spaces like sRGB, Adobe RGB, DCI-P3, or any other color gamut, they are all defined by a triangle on the CIE XY 1931 Chromaticity Diagram created by the International Commission on Illumination (CIE). On the diagram, the standard color range of DCI-P3 is represented by the green border. DCI-P3 typically employs a pure 2.6 gamma curve and a white point with a correlated daylight temperature like D63 but with a greener hue.
DCI-P3 color coverage is displayed as a percentage (e.g., 70% DCI-P3, 85% DCI-P3, ...). Additionally, DCI-P3 has a color gamut wider by 25% compared to sRGB and can handle 10-bit color, providing more colors, resulting in richer and more vibrant images, which is also the key to HDR. Speaking of HDR, DCI-P3 is also the color space used by HDR.
3. DCI-P3 vs sRGB and Adobe RGB
sRGB stands for Standard Red Green Blue (where RGB stands for Red Green Blue). Developed by HP and Microsoft in 1996, sRGB aims to standardize color representation on electronic device screens. It is the most widely used color space today and is supported by most operating systems, software, PCs, and printers... sRGB is also the only color gamut supported by web browsers.
Adobe RGB is a color space developed by Adobe Systems in 1998, optimized for CMYK color space used in printing. Adobe RGB covers about 50% of the CIE XYZ color space, which means its color gamut is wider than sRGB, only about 30%. Adobe RGB has a wider color range towards the green direction compared to sRGB, allowing for more saturated color expression.
While sRGB represents the conventional color gamut, DCI-P3 sets the standard for cinema and Adobe RGB for the printing industry. Despite not being an international standard, Adobe RGB is widely used in professional environments due to its rich color spectrum, enhancing the allure for software users like Adobe Photoshop.
In terms of compatibility, the DCI-P3 color standard is compatible with all digital cinema projectors. Moreover, with approximately 25% more color coverage than sRGB, DCI-P3 offers a broader range of colors and more lifelike images. Additionally, if you seek to fully experience HDR, DCI-P3 stands as an excellent choice. Furthermore, DCI-P3 can utilize 10-bit color depth compared to sRGB's 8-bit, presenting another advantage.
DCI-P3: The Space of the Future
Since its development for digital media usage, the DCI-P3 color gamut has garnered more favor compared to Adobe RGB and sRGB. Designers now have additional space for creative freedom, while it's undeniable that sRGB's color is good, DCI-P3's hues are even more vibrant and sharp. Moreover, the rising popularity of HDR imagery has propelled the demand for wider color spaces from gaming to TV programs. It's for this reason that an increasing number of screens support this color space to deliver richer hues.
