What is a color gamut?
A color gamut defines the range of colors a display can reproduce. Think of it as the palette available to the screen. A wider gamut means the display can show more saturated, vivid colors.
The main standards
sRGB: The baseline standard for the internet, Windows, and most consumer content. Covers about 35% of visible colors. If your work is only displayed on screens and the web, sRGB is all you need.
DCI-P3: About 25% wider than sRGB. Used in cinema, Apple devices, and increasingly in HDR content. Provides noticeably more saturated reds, greens, and oranges.
Adobe RGB: About 35% wider than sRGB, but in different directions than DCI-P3. Adobe RGB covers more cyan and green tones. Mainly relevant for print work and professional photography where CMYK color reproduction matters.
Which one do you need?
Web design and general use: sRGB. The vast majority of web content and applications use sRGB. A monitor with 99%+ sRGB coverage is ideal.
Video editing and content creation: DCI-P3. Modern video standards (HDR10, Dolby Vision) use DCI-P3 as the target color space. 95%+ DCI-P3 coverage is recommended.
Print work and photography: Adobe RGB. If your work gets printed, Adobe RGB coverage ensures you can preview colors that exist in CMYK print gamuts but fall outside sRGB.
The oversaturation problem
When a wide-gamut monitor displays sRGB content without proper color management, colors can appear oversaturated. Reds look radioactive, greens look neon, and skin tones look sunburned.
Always check that your OS and applications are color-managed. On macOS, color management works automatically. On Windows, you may need to create or load an ICC profile for your monitor.
How to test your gamut
Use our Color Accuracy and Color Test tools to display known reference colors and compare them visually. For precise measurements, a hardware colorimeter (like a Datacolor Spyder or X-Rite) is necessary.
