1)Color gamut
First of all, we need to clarify what exactly the concept of color gamut is. In official terms: a color gamut is a method of encoding a color, and refers to the sum of colors that a technical system can produce. In computer graphics processing, a color gamut is a complete subset of colors. The most common application of a color subset is to accurately represent a given situation. For example, a given color space or the color rendering range of a given output device.
Color gamut is expressed in percentages, such as 99% SRGB, 90% Adobe RGB, etc. The percentages indicate coverage, such as the same color gamut, 99% SRGB colors should be richer and more than 75% SRGB colors.
For non-design work of ordinary users, the purchase of color gamut indicators do not need to care. For designers, the purchase criteria are as follows.
- Regular graphic design, UI design, PS, etc.: Meet one of SRGB99%, SRGB100%, or NTSC72%.
- High-end commercial advertising, exhibition, and curatorial-grade print work: Use Adobe RGB color gamut and meet SRGB125% or NTSC110%.
2)Dark color
Color depth is the color depth, mainly 8it, 10bit depth, 8bit = 16.7 million colors, 10bit: 1.07 billion colors. The greater the color depth, the greater the number of colors displayed, as shown in the gradient color transition is more natural and smooth.
For regular graphic design, UI design, PS, etc., 8bit is also enough, and you can choose 10bit if you have higher requirements for color.
