Color gamut is the range of colors a display can reproduce. Wider gamuts can show more saturated colors, important for photo editing, video work, and HDR content.
Common standards: sRGB (web/general use, smallest), DCI-P3 (cinema, ~25% wider than sRGB), Adobe RGB (print photography), Rec.2020 (HDR/4K UHD, very wide, hard to fully cover).
Coverage values like "100% sRGB" or "98% DCI-P3" describe how much of each gamut a display reproduces. Creators look for ≥95% DCI-P3 for HDR work and ≥99% Adobe RGB for print prepress.
Most flagship phones cover 100% DCI-P3. Budget displays often only cover 70–90% sRGB. Always check the % coverage, not just the gamut name.
