Colour Gamuts: sRGB vs DCI-P3 vs BT.2020 — Why Colours Pop 🎨📺
🎯 Quick Summary
Color gamuts define the range of colors a display can reproduce. sRGB is the standard for web/office use (narrow). DCI-P3 offers 25% more colors, great for content creation and movies. BT.2020 is the future HDR standard with massive color range. Wider gamuts = more vibrant colors, but content must support them.
🎨 1. Color Gamut Fundamentals
What's a color gamut? Imagine all visible colors as a massive triangle. A color gamut is a smaller triangle inside that shows which colors your display can actually produce. Wider gamut = more colors = more vibrant images (when content supports it).
🔬 The Science
- • Defined by primary colors (RGB)
- • Measured on CIE 1931 chart
- • Hardware limitations matter
- • Software must support it
📏 Coverage Numbers
- • "98% sRGB" = excellent web use
- • "90% DCI-P3" = good for media
- • "76% BT.2020" = HDR capable
- • Higher % = better gamut
🎯 Real Impact
- • More saturated greens/reds
- • Better sunset colors
- • Richer skin tones
- • Vibrant nature photography

❓ Frequently Asked Questions
Q: Is wider color gamut always better?
A: Not always. For web browsing and office work, accurate sRGB is more important than wide gamut. Wide gamut can make sRGB content look oversaturated if not properly managed. Quality of implementation matters more than gamut size.
Q: Why do some "100% sRGB" displays still look dull?
A: Coverage percentage doesn't tell the whole story. Poor calibration, low brightness, bad contrast ratios, or cheap panels can make even wide-gamut displays look washed out. Color accuracy and display quality matter more than raw specifications.
Q: Should I trust manufacturer gamut claims?
A: Be skeptical. Many manufacturers exaggerate gamut coverage or cherry-pick favorable measurements. Look for third-party reviews with actual colorimeter measurements. Professional review sites like DisplayMate or RTINGS provide accurate data.
Q: Can I convert sRGB content to look good on wide gamut displays?
A: Modern devices should handle this automatically through color management. Your display should have an sRGB mode that clamps the wide gamut to sRGB standards. If colors look oversaturated, your display lacks proper color management.
Q: Is DCI-P3 worth the extra cost over sRGB?
A: For creative work, photo editing, or media consumption, yes. The improvement is noticeable, especially in colorful content. For office work only, the difference is minimal. Consider your primary use case and budget.
Q: How important is BT.2020 coverage right now?
A: For most users, not very important yet. Even 70% BT.2020 coverage is considered good for HDR displays. Focus on good DCI-P3 coverage and HDR support. Full BT.2020 is still years away from mainstream relevance.
