Color Screen
Turn your display into any solid color. Pick a color, open it full screen for a flat edge-to-edge field, or download it as an image in 480p, 720p, 1080p, 1440p, 4K or any size you type in — free, no sign-up, nothing uploaded.

What a color screen is for
A "color screen" is just a browser page filled with one solid color, but a flat field of color is a surprisingly useful tool. A white screen is a light source — for tracing, video-call fill light or checking a monitor for dust and dead pixels. A black screen saves power on OLED phones and shows up backlight bleed on an LCD. A red screen protects night vision for astronomy; a green screen is a compact chroma-key backdrop; a blue screen is classic bias lighting behind a TV. Any color makes a clean background for photos, streams and signage, or ambient lighting for a room.
Which color screen should I use?
| You want to… | Use | Why |
|---|---|---|
| Check a monitor or phone for dead pixels | White, black, then red, green, blue | Each field isolates one kind of fault — see the test sequence below. |
| Find backlight bleed or IPS glow | Black screen | Light leaking at the edges only shows against true black in a dark room. |
| Save battery on an OLED phone | Black screen | Black OLED pixels are switched off and use no power. |
| Light your face on a video call | White or a warm peach screen | A bright, soft field works as a small softbox; warmer tones flatter skin. |
| Keep your night vision | Red screen, dimmed | The eye stays dark-adapted under dim red light. |
| Key yourself out on video | Green or blue screen | Saturated green and blue are the standard chroma-key colors. |
| Bias light behind a TV | White or a cool blue screen, dimmed | Raising the light behind a screen eases eye strain in a dark room. |
| Relax or set a mood | Lavender, sage, orange or any soft color | Muted and warm colors are easy on the eyes as ambient light. |
| Judge panel uniformity and tint | Gray screen | A mid-gray field shows clouding and color tint more clearly than white. |
Dead pixel test: the 5-screen sequence
- White screen — every sub-pixel is on, so a dead pixel shows as a black or colored dot. Also look for dust and uneven brightness.
- Black screen — every sub-pixel is off, so a stuck pixel shows as a bright dot. On an LCD, check the edges for backlight bleed.
- Red, green and blue screens — each lights one sub-pixel color only, which tells you exactly which sub-pixel has failed.
Open each one full screen, set the display to full brightness and look closely from about 30 cm, section by section. A pixel that is the wrong color on one screen but fine on the others is a stuck sub-pixel and sometimes recovers; one that is dark on every screen is dead. The cyan, magenta and yellow screens are useful extra checks, because each switches one sub-pixel color off.
How to use it
- Choose a color — use the color box, type a hex code or a color name, or tap one of the quick swatches. Every named color below also has its own page.
- Choose a resolution — tap a preset (480p to 4K), pick an aspect ratio, or type an exact width and height. Fit my screen matches your device.
- Preview — the panel shows the exact size and color.
- Open full screen — the whole display fills with the color. Press Esc or tap to exit.
- Download — save it as a PNG or JPG at the size you set.
- Share — post the exact color screen, with a matching preview image, to Pinterest, Facebook, X, Reddit or WhatsApp.

Custom sizes go up to 16384 px on each side — common choices are 1080 × 1920 for phones, 1080 × 1080 for social posts and 3840 × 2160 for 4K TVs. The Advanced panel writes a real DPI into the PNG for print. Downloads are generated in your browser, so nothing is uploaded and there is no watermark.
Using a color screen on any device
Phone & tablet — open the page and tap Open full screen; on iPhone and iPad, turn auto-lock off first if you want the screen to stay on. Laptop & desktop — full screen hides the taskbar and menu bar for a true edge-to-edge field; drag the window to a second monitor first if you want it as bias lighting. TV & projector — open the page in the TV's browser, or download the 4K image and play it from a USB stick or a casting app for a rock-steady color that never times out.

Color screen FAQ
Is the color screen tool free?
Yes — every color screen is free with no sign-up, no watermark and no limit. The full-screen view and the downloadable images are generated entirely in your browser, so nothing you choose is uploaded anywhere.
How do I make my whole screen one solid color?
Open the tool (or any single-color page like the white screen or black screen), pick your color and resolution, then tap Open full screen. Your browser fills the entire display and hides its own bars. Press Esc or tap the screen to exit. It works on phones, tablets, laptops, desktops and most smart-TV browsers.
What resolutions and sizes can I download?
Presets cover 480p (854×480), 720p (1280×720), 1080p (1920×1080), 1440p (2560×1440) and 4K (3840×2160), in 16:9, 16:10, 21:9, 4:3, 3:2, 1:1 or 9:16. You can also type any custom width and height up to 16384 px, and set a real DPI value that is embedded in the PNG for print.
Which color screen is best for saving battery or checking a display?
A black screen saves the most power on OLED and AMOLED phones and reveals backlight bleed on an LCD. A white screen is best for finding dead pixels, dust and backlight problems. Pure red, green and blue screens each test one set of sub-pixels. A red screen protects night vision, and a dim blue screen is common as bias lighting behind a TV.
Can I use a green screen from this tool for video?
For a small area, yes — fill a spare monitor, tablet or TV with the green screen and key it out in OBS, Zoom or a video editor. For a full-body chroma key a matte green cloth still works better because it avoids on-screen reflections.
