Why Use a Purple Screen?

• Check Red-Blue Subpixel Balance: A purple screen reveals mismatches between red and blue channels, which can cause a display to look too warm or too cool.
• Find Stuck Pixels: Stuck subpixels that only appear during mixed red-blue activation become visible on a purple background.
• Test Display Uniformity: It can highlight tinting issues that are not obvious with primary colors alone.
• Evaluate Grayscale Rendering on Colored Fields: A purple screen can help you notice if text or UI elements take on a color cast when displayed over a purple background.
• Decorative Lighting: Use it as a purple accent light for gaming setups, video calls, or casual photography.

1. Start: Click the button or tap the preview to open the full purple screen.

Why Purple Is Useful for Mixed-Channel Testing

Purple depends on both red and blue working together, so it is a strong test color for mixed-channel balance. If either channel is weak or uneven, purple often shifts noticeably toward the stronger one, making tint problems easier to confirm.

Purple is also a good bridge between technical testing and visual use because it is common in wallpapers, streaming backgrounds, and decorative lighting. That makes it a practical way to judge both channel balance and how attractive mixed cool-warm colors look on the panel.
