Vérificateur de Précision des Couleurs

Why Should You Run This Test?

If your photos look different when printed, your designs don't match client expectations, or skin tones look unnatural in your edits — your monitor's color accuracy may be off. This test provides 12 reference swatches (primaries, grays, and skin tone) so you can visually check whether your display renders standard colors correctly.

Common Symptoms

• Printed photos look different from screen — colors are shifted or too saturated
• Brand colors look wrong — client's specific Pantone colors appear different on your monitor
• Skin tones look orange, pink, or gray instead of natural
• Whites look bluish, yellowish, or pinkish instead of neutral

What Causes Inaccurate Colors?

Monitor Factors

• Factory calibration quality — Budget monitors may have Delta E >5 out of the box. Professional monitors (e.g., BenQ SW, EIZO) are factory-calibrated to Delta E <2.
• Color gamut mismatch — A wide-gamut monitor (DCI-P3, Adobe RGB) will show over-saturated sRGB content unless color management is enabled.
• Aging panel — Monitor color accuracy drifts over time. Professional users recalibrate every 2-4 weeks.

Settings & Environment

• Incorrect color profile — Using the wrong ICC profile causes systematic color shifts. Check Display Settings → Color Management.
• Color temperature set wrong — Monitor OSD color temp affects white balance. Use 6500K (D65) for standard work.
• Ambient lighting — Warm room lighting makes your screen look blue by comparison, and vice versa. Test in consistent, neutral lighting.

How to Read Your Results

How to Improve Color Accuracy

• Set color temperature to 6500K — In your monitor's OSD menu, set color temp to 6500K (D65) or "sRGB" mode for standard work.
• Install the correct ICC profile — Download your monitor model's ICC profile from the manufacturer's website. Apply it in Display Settings → Color Management.
• Enable sRGB mode — If your monitor has a wide color gamut (DCI-P3, Adobe RGB), enable sRGB clamp mode for web work to prevent oversaturation.
• Calibrate with hardware — For professional accuracy, use a colorimeter (e.g., Datacolor SpyderX, X-Rite i1Display) to create a custom ICC profile. Recalibrate every 2-4 weeks.
• Check ambient lighting — Test in neutral, consistent lighting. Avoid warm or colored room lights that bias your color perception.
• Set brightness to 120 cd/m² — For print-matching work, set monitor brightness to 120 cd/m² (about 40-60% on most monitors).
