What is color space? The difference between sRGB and Adobe RGB

The word "color space" originated from the western "color space", also known as "color gamut". In chromatics, people have established a variety of color models, using one-dimensional, two-dimensional, three-dimensional or even four-dimensional space coordinates to represent a certain color, and the color range that can be defined by this coordinate system is the color space.

A color space is a series of colors. Jpeg, a compression format, can contain 654.38+06.7 million colors at most, but no color space has been used to complete 654.38+06.7 million colors. Color space allows users to use a wider or narrower range among 6.5438+0.67 million colors, but where the two colors are set differently, one can get a wider color range and the other becomes a narrower color range.

Difference:

1, development time is different.

SRGB color space: 1997

AdobeRGB color space: 1998

2. Different manufacturers

SRGB color space: jointly developed by Hewlett-Packard and Microsoft.

AdobeRGB color space: Adobe Company, USA

3. Different color ranges

AdobeRGB has 35% more color range than sRGB, so the photos will be more colorful. Adobe RGB is richer in color, including all the colors of SRGB.

4, the saturation is different

AdobeRGB has higher red and green saturation than sRGB, and AdobeRGB is brighter than sRGB.

Extended data

"sRGB" means "standard RGB color space" and is widely used. Many other hardware and software developers also adopt sRGB color space as the color space standard of their products.

Such as Internet, games, applications, laptops, etc. Almost all standards use sRGB as the color space standard. Traditional monitors can only display about 97% sRGB color space and about 76% AdobeRGB color space.

Adobe RGB is an important standard for high-performance displays, but for displays, the higher the Adobe RGB value, the better the display effect.

The higher the Adobe RGB of the display, the lower the color bit and sRGB standard. Adobe RGB standard of BenQ Ez2450L is 95%, but the color bit is only 6bit and sRGB is only 100%. On the contrary, there will be problems such as uneven color transition, tearing and color cast in the picture.
