Wide Color Gamut (Display P3) Target Test

Hardware Gamut Inspector

Modern Apple devices, OLEDs, and HDR creator displays support the DCI-P3 color space, displaying reds that are ~25% more saturated than standard sRGB. In the swatch below, the inner square is styled in pure color(display-p3 1 0 0) and the outer frame is in rgb(255, 0, 0).

P3 LOGO

How to interpret this test:

Can you see the inner square? If the center square appears distinctly more vibrant or different from the outer frame, your display natively supports Wide Color Gamut (Display P3).
Both look identical? Your display is calibrated to standard sRGB (or your browser does not have wide-gamut CSS color space acceleration enabled).
