Color Accuracy Test Online
Are your colors accurate or oversaturated? This color accuracy test fills the screen with pure primary and secondary colors so you can judge saturation, accuracy, and gamut by eye — free, in your browser.

How to Judge Color Accuracy
"Accuracy" means colors look the way they should — neither washed out nor neon. Use a reference you trust (a photo you know well) alongside these pure colors.
Compare to memory
Show a familiar photo of a person or landscape next to the pure colors. If skin looks sunburnt and grass looks neon, the screen is oversaturated.
Check the mode
Test in sRGB or Standard mode. "Vivid" and "Gaming" modes deliberately oversaturate — never use them as a color reference.
Warm up first
Panel color and brightness drift when cold. Let the monitor warm up 15–30 minutes before judging accuracy.
Color Gamuts Explained
sRGB
The standard for the web and most content. Every monitor covers it; accurate sRGB is what matters most for everyday use.
Adobe RGB
A wider gamut used in professional photography, with richer greens and cyans. Only relevant for print/photo work.
DCI-P3
A wide gamut common in HDR and cinema content, with richer reds and greens. More coverage = more vivid, cinematic color.
A wider gamut only helps if your content and settings actually use it. For the web, a well-calibrated sRGB mode looks the most natural.
Color Accuracy Test FAQ
Why do my colors look too vivid?
Most likely you're in a "vivid" or "gaming" picture mode, which deliberately oversaturates for a punchy showroom look. Switch to sRGB or Standard mode and compare a photo you know — colors should look natural, not neon.
Do I need a wide-gamut (DCI-P3) monitor?
Only for HDR, cinema, or design work. For general web and office use, accurate sRGB is more important than gamut width — a well-calibrated sRGB screen looks better than a miscalibrated wide-gamut one.
Can I trust my eyes for color accuracy?
Roughly, yes — especially when comparing to a familiar photo. For precise, repeatable accuracy you need a hardware colorimeter, but visual checks catch the common problems (oversaturation, tint, wrong mode).
Should I calibrate my monitor?
If you do photo, video, or design work, yes — calibrate with a hardware tool for true accuracy. For everyday use, a factory reset plus sRGB mode and comfortable brightness is plenty.
