Warm-color uniformity
Compare orange tone across the full panel.
Orange Screen
Use a full-screen orange field to inspect warm-color uniformity, mixed subpixel behavior and screen tint.
What is a orange screen used for?
An orange screen provides a mixed warm color that can reveal uneven red and green output, color tint and pixels that behave normally on primary colors but fail on intermediate tones.

Useful checks with a orange screen
Intermediate-color check
Inspect mixed-color behavior beyond red, green and blue.
Stuck-pixel confirmation
Look for points that remain black, white or another color.
Warm ambient background
Use a comfortable orange field for simple background lighting.
How to use this screen safely
- Clean the display gently according to the manufacturer’s instructions.
- Use your normal viewing distance and brightness first.
- Open full screen and inspect the center, edges and corners.
- Repeat the check with black, white, red, green, blue and gray backgrounds.
- Do not stare at an uncomfortable brightness or color for a prolonged period.

Frequently asked questions
Why test orange after primary colors?
Intermediate colors can expose transition or channel-balance problems that are less obvious on pure red, green or blue.
Is the orange color calibrated?
No. The page requests a specific web color, but actual output depends on your hardware and color settings.
Can orange identify burn-in?
It may make retained shapes visible, but gray, red and other solid colors should also be checked.
Try another screen color
Run several colors because different pixel and uniformity problems appear on different backgrounds.
