Tools — Fullscreen Colors & Display Utilities
The tools index lists every interactive page on Fillhex—from pure black #000000 and white fills to OLED diagnostics and streaming lighting.
Each tool opens in the browser without installation and shares fullscreen shortcuts documented in how-to-use.
Pick a category below mentally as you browse: color fills, display tests, lighting, generators, and novelty effects.
Solid color screens
Black, white, RGB primaries, pastels, gray, and cyan pages provide instant fullscreen references for creators and technicians.
Display diagnostics
Dead pixel test, backlight bleed test, and OLED burn-in test guide inspection workflows with related guides in the Guides section.
Lighting for people on camera
Zoom Light and Ring Light turn spare monitors into soft fill sources for calls and short recordings.
Automation and messaging
Color slideshow cycles test patterns; message display shows custom text on solid backgrounds for events.
Downloads and wallpapers
Download presets and wallpaper-generator create offline PNGs when browsers are not available on test benches.
Novelty and simulation
Broken screen, no signal, and matrix pages offer stylized fullscreen effects for demos and content—use responsibly in public spaces.
