What a turquoise screen is for
Turquoise sits between green and blue at high brightness, in the region where the eye is most sensitive to small shifts. That makes it unusually good at exposing uneven backlighting, because any dimming across the panel shows up as a visible change in tone rather than just brightness.
A stone coloured by copper
Turquoise gets its colour from copper in the mineral, and its variations from iron: more copper pushes it blue, more iron pushes it green. The name came through French, meaning Turkish, because the stone reached Europe by way of Turkey rather than being mined there. It is one of the oldest gemstones in recorded use, appearing in Egyptian and Persian work thousands of years ago, which is largely because it is soft enough to shape with simple tools.
The blue-green naming problem
Turquoise sits in the region where blue and green stop being clearly separable, alongside teal, cyan and jade. Where any individual draws that boundary varies, and languages differ in whether they treat blue and green as one category or two, so descriptions of colours in this band are unusually unreliable. Turquoise is lighter and brighter than teal and less pure than cyan, which is a real distinction that is much easier to see than to read.
As a bright, cool field
Turquoise combines green and blue at high output with a little red, which makes it one of the brighter colours a display produces and gives it a distinctly cool cast as a light source. It takes dark text well and white text poorly. For a wallpaper it is vivid enough to be a deliberate choice rather than a neutral one, and at full brightness a large area of it is tiring in the way any saturated bright colour is.

Turquoise color values
The exact values for this shade, if you need to match it somewhere else.
| Hex | #40E0D0 |
|---|---|
| RGB | 64, 224, 208 |

Contrast ratios follow the WCAG formula. Anything at or above 4.5:1 is readable as body text against that background, and 3:1 is the floor for large headings. Turquoise reaches that bar on black.

Questions
Does this work on a phone?
Yes. On mobile the page fills the screen when you tap the panel. Some browsers keep a thin status bar visible, which is a browser limit rather than something the page controls.
Will a turquoise screen fix a stuck pixel?
Sometimes. A stuck pixel is lit in one color and can occasionally be freed by cycling colors rapidly for a few minutes. A dead pixel receives no power at all and cannot be recovered in software.
What is the hex code for this turquoise screen?
This page uses #40E0D0. The same value is shown in RGB, HSL and CMYK further down, so you can match this exact shade somewhere else.
Does a turquoise screen save battery?
No, and on an OLED or AMOLED screen a light color costs more power than a dark one, because every pixel has to be lit. If battery life is the goal, use the black screen instead.
Can I download this turquoise as a wallpaper?
Yes. There is a ready-made 1920 by 1080 PNG on this page, and the panel above will generate the same color at your own screen size, at 1440p or 4K, or at phone dimensions. No watermark and no sign-up.
Is it free?
Yes, and there is no sign-up. The page draws a color; that is the whole tool.
