DCI-P3
DCI-P3 is a range of colours, wider than sRGB, that a screen can be rated to show.

DCI-P3 is a colour space, which is a defined range of colours that a screen can show. It was created for digital cinema projection by the Digital Cinema Initiatives group and is now widely quoted for phones, tablets, laptops, monitors and televisions. Its range is roughly a quarter wider than sRGB, mainly in reds and greens.
How it works
No screen can show every colour the eye can see. A colour space marks the edge of the colours it can reproduce, using three corner points for red, green and blue. DCI-P3 places those corners further out than sRGB, so deeper reds and greens are possible. A variant called Display P3 keeps the same colours but uses the white point and brightness curve of sRGB, which suits everyday screens.
What the numbers mean
- Coverage is shown as a percentage. 95 percent DCI-P3 coverage means the screen reaches 95 percent of that colour range.
- Coverage and volume are different measures, so the two figures cannot be compared directly.
- Photos and videos need to be made in P3 for the extra colours to appear.
What it does not promise
A wide colour range is not the same as accurate colour. Accuracy is how close the shown colours are to the intended ones, and it is measured separately. Content made in sRGB can look over-saturated if a screen shows it without converting it. Coverage figures are usually claimed by the maker.
