what is the wavelength of visible light
Red is transmit and It absorb green blue and cyan.
First, let's understand why you call that device a 'cyan filter'? Was it invented by the famous Austrian Physicist Professor Cyril Cyan? Is it marketed and distributed in the US by the Cyan Filterwerks? Or is it because when you look at it, it looks the color of cyan? Could that be because whatever color of light enters one side of the filter, the only color of light that's not absorbed by the filter and remains to come out the other side is cyan light? In that case, whenever cyan light is present in the incident light ... like if it's 'white' light ... then the cyan comes out the other side and the filter looks cyan. And if there's no cyan in the incident light, then all of it is absorbed in the dyes in the filter, and the other side of the filter appears very dark, or black.

White, as Cyan in blue and green, add red you then have all three colours hence white.
Red is transmit and It absorb green blue and cyan.
Try these: #E0FFFF - LIGHT CYAN #00FFFF - TRUE CYAN #57FEFF - CYAN 1 #50EBEC - CYAN 2
In light, it is the color you get when you mix blue and green.
Toner is a powder used for laser printers. It is not to be confused with printer ink. Toner cartridges to be used for color printing come in cyan, magenta, yellow, and black.
The HP Q6001A toner cartridges are available in cyan, magenta, yellow and black.
Cyan is an equal mix of blue and light green.
The LaserJet 3600 uses the following ink cartridges: HP 501A Black Toner, HP 502A Cyan Toner, HP 502A Magenta Toner, and HP 502A Yellow Toner cartridges.
When talking about color printer toner the letters CMYK refer to the colors Cyan, Magenta, Yellow, and Key all part of the toner itself. Key is almost always a black, however it can be other colors at times.
