Screen Test Colors (10 effects)

Full-screen solid colors for testing your monitor for dead pixels, stuck pixels, color accuracy, and uniformity.

⬜ WhiteBright white screen — reveals dead (black) pixels that stay dark.
⬛ BlackPure black screen — reveals stuck (bright) pixels that stay lit.
🟥 RedFull red — tests the red sub-pixel layer of your display.
🟩 GreenFull green — tests the green sub-pixel layer.
🟦 BlueFull blue — tests the blue sub-pixel layer.
🟨 YellowFull yellow — reveals blue sub-pixel defects (yellow = red + green).
🟧 OrangeFull orange — tests warm color rendering.
💗 PinkFull pink — tests magenta/pink color accuracy.
🟪 PurpleFull purple — tests violet/purple rendering.
🩶 Gray50% gray — reveals banding, uniformity issues, and backlight bleed.

Retro TV Effects (4 effects)

Nostalgic simulations of classic television and video artifacts.

📺 TV StaticRandom black and white noise — the classic "no signal" snow pattern from analog TVs.
🌈 Color BarsSMPTE broadcast test pattern with 7 color bars — the standard TV calibration card.
📼 VHS GlitchAnalog video distortion with color shifts, horizontal tearing, and scanline artifacts.
🖥️ CRT ScanlinesMoving horizontal scanline overlay on a dark screen — simulates a CRT monitor.

Classic Screensavers (5 effects)

Beloved screensavers from the golden age of computing, recreated in your browser.

🔢 Matrix RainGreen falling characters inspired by The Matrix — katakana, Latin letters, and numbers cascade down the screen.
✨ StarfieldWarp speed flight through a field of stars — the classic space travel screensaver.
💿 DVD LogoThe iconic bouncing DVD logo that changes color every time it hits a wall.
🔮 MystifyColor-shifting bouncing polygons that leave trails — the Windows Mystify screensaver.
🔧 3D PipesColorful pipes that grow and turn randomly across the screen — a Windows classic.

Modern Effects (2 effects)

🌀 PlasmaAnimated mathematical plasma wave patterns with smooth color gradients — optimized for 4K displays.
🎨 Gradient MeshDynamic multi-color gradient animation with smoothly moving radial color spots.

Math Art (4 effects)

Beautiful mathematical patterns and visualizations brought to life with animation.

🌀 FibonacciThe golden spiral and fractal geometry — Mandelbrot-inspired particle rings, golden ratio lines, and fractal tree branches on a cosmic background.
📊 InfographicAn educational illustration showing Fibonacci squares with labeled numbers, the golden spiral overlay, and fractal branching patterns.
∞ LissajousSmooth intersecting sine wave curves forming symmetrical loops — oscilloscope-style with glowing neon lines in blue, pink, green, and gold.
🌸 Polar RoseFlower-like geometric petals formed by polar rose curves — evolving symmetrical patterns with soft gradient colors.
