Purple color and hue testing
Deep purple (#800080) drives red and blue hard with little green — a fast way to spot hue skew, 8-bit banding, and mixed-channel defects.
Purple screen for display inspection
Look for patches that look too blue, too red, or blotchy. Uniform purple should look even from center to corners at normal viewing distance.
How to use purple to check color uniformity
Compare left vs right and top vs bottom. Tint that shifts with viewing angle may be panel technology; fixed blotches can indicate backlight or coating issues.
About Purple Screen Test
Use a free fullscreen purple screen test to check hue balance, color uniformity, and display rendering on monitors, phones, tablets, and TVs.
Why purple stresses red and blue together
Unlike pure red or blue tests, purple activates both channels at once. That reveals imbalance single-primary screens miss — for example a panel that looks fine on red but drifts cyan-ish when blue joins.
Purple vs white and black in a full pixel pass
Use white for dark dead pixels, black for bright stuck pixels and bleed, then purple for mixed-channel hue and banding. Start pixel test cycles white, black, and RGB; return here when you need a dedicated purple field.
OLED and LCD behavior on purple
OLED can render deep, saturated purple with high contrast against dark UI chrome. LCD black levels lift the perceived richness — a milky cast under purple often tracks with elevated black level or local dimming quirks.

Core testing tools
Continue your display QA with these linked diagnostics.
Dead pixel test → Solid-color fullscreen frame-by-frame scan. Detects bright, dark, and stuck pixels — the essential first step. Backlight bleed test → Pure black fullscreen in a dark room to detect LCD leakage and IPS glow. Color calibration test → Gamma ramps and greyscale steps for accuracy checks. Color gamut test → sRGB vs Display P3 patches for wide-gamut verification. Refresh rate test → Real-time Hz detection to verify your panel's actual refresh rate. Ghosting test → Moving blocks for response time and grey-to-grey transition speed. Uniformity test → Grey fields and grid overlay for vignette and tint checks. Display test center → Hub for customizable display QA — gradients, HDR, flicker, and more.
Purple screen tips
-
Why purple stresses red and blue together
On 6-bit+FRC or weak 8-bit panels, smooth purple fields often show banding bands. If you see steps, note whether they stay fixed when you move your head (panel/processing) vs shifting with angle.
-
Purple vs white and black in a full pixel pass
Creators and calibrators also use purple as a sanity check after changing color temperature or gamut modes — if purple suddenly looks magenta or indigo, the profile may have shifted.

OLED and LCD behavior on purple
If purple looks crushed or posterized only in HDR or game modes, switch to a standard SDR mode and retest before blaming the panel.

Purple screen FAQs
What is a purple screen test?
A purple screen test fills the display with solid purple so you can inspect red–blue channel balance, hue uniformity, and banding. TestMyGears offers a free purple screen online — open fullscreen on this page for an instant check.
Why test with purple instead of only RGB?
Purple exercises red and blue together. Issues that hide on single-channel red or blue — mixed tint, banding, and uneven saturation — often show clearly on a full purple field.
How do I check color uniformity with a purple screen?
Enter fullscreen, stand at normal viewing distance, and compare corners to the center. Fixed blotches or a left/right hue shift can indicate uniformity problems; angle-dependent shifts may be normal for the panel type.
Can I download a purple screen wallpaper?
Yes. Choose 1080p, 4K, 8K, or custom dimensions, then download a PNG purple wallpaper for presentations, streams, or desktop backgrounds.
Is purple useful for OLED vs LCD?
Yes. OLED usually shows deeper, cleaner purple; LCD elevated blacks can make purple look washed. Compare this page with our black and white screens for a fuller picture.
How does this relate to the screen colors hub?
The screen colors hub is the quick switcher for every preset in one place. This purple screen page keeps a steady purple field with purple-specific tips when you want to stay on one color.
Free to use?
Yes — TestMyGears is free with no account required.
