Cyan Screen
Cyan is green and blue at full power with red off — the exact complement of red, and one of the four process inks in CMYK printing. It is bright, cool and unmistakably digital.
What people use the cyan screen for
Cool key or rim light
Cyan reads as moonlight or screen-glow on camera. Pair it with a warm source on the opposite side for the orange-and-teal look.
Print colour reference
As one of the CMYK process inks, a flat cyan field is a rough on-screen reference when you are eyeballing a print proof — with the usual caveat that a backlit screen and inked paper never match exactly.
Check green and blue together
Cyan exercises the green and blue sub-pixels at once while red stays dark, isolating a different pair than magenta or yellow do.

Frequently asked questions

What is the exact cyan colour used here?+
#00FFFF. You can copy it from the control bar, or open the colour picker to dial in any other value and keep it in the URL so the exact shade is bookmarkable.
