Is DCI-P3 better than sRGB?

As mentioned in the article above, DCI-P3 has 26% more color space than sRGB. This means DCI-P3 offers a greater range of colors at a more saturated and vibrant level. It can use up to 10-bit color as compared to sRGB’s 8-bit, allowing users to enjoy HDR content in even more colors.

What color space should I use?

sRGB is an RGB color space that was developed by Microsoft and HP for digital use. It’s the most appropriate color space for computer screens and other digital devices, like tablets and smartphones.

What is chromaticity diagram & Color circle diagram?

The chromaticity diagram is thus a normalized plot of the color response of the CIE 1931 standard observer. Each point on the curved boundary line in Figure 6.4–5 is plotted from the tristimulus values that result from a single-wavelength stimulus.

What is luminance and chromaticity?

Chromaticity is an objective specification of the quality of a color regardless of its luminance. Chromaticity consists of two independent parameters, often specified as hue (h) and colorfulness (s), where the latter is alternatively called saturation, chroma, intensity, or excitation purity.

What is L in Lab color space?

The Lab Colour Space Revisited It’s comprised of three axes: L represents darkness to lightness, with values ranging from 0 to 100; a represents greenness to redness with values of -128 to +127; and b represents blueness to yellowness also with values from -128 to +127.

What are tristimulus values?

tristimulus system, a system for visually matching a colour under standardized conditions against the three primary colours—red, green, and blue; the three results are expressed as X, Y, and Z, respectively, and are called tristimulus values. Related Topics: colour.
