What a turquoise screen is used for
- Bright, cool backgrounds for photography and video
- Cool ambient light for streaming setups
- A vivid alternative to cyan that is easier to look at
Turquoise screen online: #40E0D0 at full screen
Turquoise is #40E0D0 — green and blue high with a little red mixed in, which takes the harsh edge off pure cyan while keeping most of its brightness. That small amount of red is what makes it read as a natural colour rather than a display primary.
Because all three channels are active it is not a channel test, but it is a good check for smooth rendering of near-saturated mixed colours, which is where narrow-gamut panels tend to clip.
On a wide-gamut display this page will look noticeably more vivid than on a standard sRGB monitor. That difference is the gamut, not the page.
How to get a full screen turquoise background
Press the fullscreen button on the player above, or the F key. Escape returns you to the page. On a desktop browser F11 does the same job and hides the browser's own toolbars as well.
The colour box is a control, not a picture: use the hex field to enter any value, pick another shade from the palette, or download the current colour as a PNG at your screen's resolution. Whatever you set is written into the address bar, so the link you copy reproduces exactly what you are looking at.
