What a amber screen is for
Amber is the classic warm display color, the tone old monochrome terminals used. It produces very little blue light, which is why it turns up in night reading modes and instrument panels.
Fossil resin, and the traffic light
Amber is fossilised tree resin, sometimes tens of millions of years old, and it is the material famous for preserving insects trapped in it while it was still sticky. The colour named after it is the warm orange-yellow of the clearer varieties. It is also the official name of the middle traffic signal in British and international usage, where American English says yellow: same light, different word, and amber is the more accurate description of the actual colour used.
Amber displays and warm light
Amber was one of the two common phosphor colours for monochrome monitors, alongside green, and it was widely preferred in some markets for long working sessions. The genuine argument for it is spectral: amber contains very little short-wavelength light, so it has little effect on the circadian system compared to a white or blue-heavy screen. That is the same reasoning behind warm night modes today, and it makes an amber field a sensible thing to have open in a dark room.
On a display
Amber is red at full output with green a little over half and blue at zero, which makes it a bright warm field with only two channels involved. That simplicity makes it a decent quick check that red and green are mixing proportionally: if amber renders as yellow the green channel is running hot, and if it renders as orange-red the green is weak. Dark text sits on it well and light text does not.

Amber color values
The exact values for this shade, if you need to match it somewhere else.
| Hex | #FFBF00 |
|---|---|
| RGB | 255, 191, 0 |
| HSL | 45°, 100%, 50% |
| CMYK | 0%, 25%, 100%, 0% |
| Contrast on white | 1.65:1 |
| Contrast on black | 12.7:1 |
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. Amber 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 amber 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 amber screen?
This page uses #FFBF00. The same value is shown in RGB, HSL and CMYK further down, so you can match this exact shade somewhere else.
Does a amber 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 amber 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.
