Hey PH community! 👋 We've added another new tool to USBRecognized — a free online Color Test for checking your monitor or display right in the browser. No installs, no signups, 100% privacy-friendly. Here's what's included: 🎨 Nine Solid Colors — Full-screen pure red, green, blue, white, black, gray, yellow, cyan, and magenta. Instantly spot dead pixels, backlight bleed, and uniformity issues. 🌈 RGB Gradient Ramps — Smooth black-to-red, black-to-green, and black-to-blue gradients that reveal color banding caused by low color depth or cheap panels. ⚡ 16-Step Grayscale Ramp — Check for color tinting (pink, blue, or green casts), shadow detail, and highlight clipping across the full tonal range. 📺 SMPTE Color Bars — Industry-standard pattern with seven primary/secondary colors, reverse bars, and a PLUGE pattern for professional-level color and black-level verification. 🎯 Custom Hex Color Input — Type any hex code to fill your screen with that exact color. Great for testing brand colors, calibration targets, or reproducing an issue you saw elsewhere. ⛶ Fullscreen Mode — Uses the Fullscreen API for an immersive, distraction-free test across your entire screen. 🩺 AI Diagnostic Summary — After testing, get a 0–100 health score, possible causes, and recommended fixes. Export as PDF, text, or a shareable URL. Works on every display type — LCD, LED, OLED, QLED, IPS, VA, TN, Mini-LED — and on any device with a browser: desktop monitors, laptops, tablets, phones, and even TVs. All testing is purely local CSS background colors; nothing is ever uploaded. Ideal for anyone buying a new monitor, checking a display before photo editing or design work, verifying color accuracy for gaming, or troubleshooting a "colors look weird" issue. Available in 11 languages. Let us know what you think! 🖥️
