Color gamut is the range of colors a display can reproduce. sRGB covers about 35% of visible colors and is the standard for web and Windows. DCI-P3 covers about 54% and is used in cinema and Apple displays. Rec. 2020 covers nearly the full visible spectrum.

How do I know if my monitor covers sRGB?

Use this test and compare the sRGB primaries section. They should appear saturated and vivid. If the red looks orange, or the green looks yellowish, your monitor may not fully cover sRGB. Most monitors since 2015 cover 95%+ sRGB.

What is wide gamut and do I need it?

Wide gamut monitors reproduce colors beyond sRGB, including the more vivid colors used in cinema (P3) and professional photo editing. For gaming and general use, sRGB coverage is sufficient. For photo editing, video production, or design work, P3 coverage (90%+) is recommended.

Why do P3 colors look the same as sRGB on my monitor?

If your monitor only covers sRGB, it cannot display P3 colors - they get clamped to the nearest sRGB equivalent. A P3 capable monitor will show noticeably more vivid reds, greens, and oranges in the second section compared to a standard sRGB monitor.

Color Gamut Test

Evaluate your monitor color gamut coverage. Compare sRGB primaries and extended P3 colors to see how vivid your display renders colors.

sRGB Primaries

Every monitor should reproduce these accurately

Vibrant Colors (needs DCI-P3 or wider)

These appear more vivid on wide-gamut displays. On sRGB monitors they are clamped.

Grayscale Neutrals

Grays should look completely neutral with no color cast

How to use

Click any color patch to view it fullscreen for the most accurate evaluation.
sRGB primaries should be vivid and saturated on any modern monitor.
P3 colors look noticeably more vibrant on wide-gamut displays.
All gray patches should appear completely neutral with no color cast.

Testing guide

How to test color gamut visually

Color gamut describes the range of colors a display can reproduce. This visual test helps compare standard sRGB patches, wide-gamut color patches, and neutral grays so you can spot oversaturation, weak primaries, or obvious color casts.

Best for

Comparing sRGB, DCI-P3, Display P3, and wide-gamut monitor behavior.
Checking whether vivid colors appear richer on a claimed wide-gamut display.
Spotting grayscale tint problems before doing photo, video, or design work.

How to run the test

1Use the monitor native color mode first, then compare with its sRGB or creator mode.
2View the sRGB primary colors and confirm red, green, and blue look clean and distinct.
3Open the wide-gamut patches fullscreen and compare whether reds and greens look more vivid.
4Check neutral gray patches for unwanted green, magenta, yellow, or blue tint.

How to read the result

If wide-gamut patches look identical to sRGB patches, the panel may be sRGB-limited or color managed tightly.

If web colors look too neon, the display may be wide-gamut without a proper sRGB clamp.

Neutral gray tint usually points to white balance or color temperature settings rather than gamut itself.

Frequently asked questions

What is the difference between sRGB and DCI-P3?

sRGB is the common web and desktop color standard. DCI-P3 is wider, especially in reds and greens, and is common on modern HDR displays, phones, laptops, and creator monitors.

Can this replace a colorimeter?

No. This is a visual check, not a measured calibration. Use a hardware colorimeter when you need accurate profiles for paid photo, video, or print work.

Why do colors look oversaturated?

Wide-gamut displays can oversaturate sRGB content when apps or system settings do not manage color correctly. Try the monitor sRGB mode for normal web use.
