Projector Color Temperature Test — White Balance Calibration
Free fullscreen colour-temperature test for projectors. Eight Kelvin points (2700K, 3200K, 4000K, 5000K, 5500K, 6500K/D65, 7500K, 9300K) are computed from the Planckian locus and rendered as full-screen colour fields. Compare visually against a known white reference (paper, calibrated monitor) or measure with a colorimeter for precise white-balance calibration.
How to calibrate white balance
1
Start at D65
Project the 6500K field. This is the cinema/broadcast standard — your image should appear neutral white here.
2
Compare neighbours
Step to 5500K and 7500K. The transition should be smooth and predictable.
3
Adjust in OSD
If D65 looks tinted, adjust the projector's colour temperature menu and re-check.
Eight calibrated full-field colour temperatures for visual white balance
D65 (6500 K) is the broadcast/cinema standard — your projector should look neutral here. Other points let you compare. Use a colorimeter for precise calibration.
