What a teal screen is used for
- Calm, cool ambient light at low intensity
- Backgrounds for photography where cyan is too vivid
- Checking green and blue at mid output with red confirmed off
Teal screen online: #008080 at full screen
Teal is #008080, cyan at half output. It keeps cyan’s diagnostic value — red is at zero, so any red or pink dot on this field is a stuck subpixel — while being far easier to look at than full cyan, which is one of the most intense colours a display can produce.
It is a common interface colour for the same reason: cool and distinctive without demanding attention. As ambient screen light it reads as calm rather than clinical.
Teal, olive, maroon and navy are all the same idea — a primary or secondary at half output — and together they make a decent mid-tone test sweep across all six hues.
How to get a full screen teal 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.
