Because those three colours can mix together to create other colours

Why do the digital sensors in a camera only need to detect three different colours?
Photographs can be taken using film or sensors that can detect ultraviolet light. These photos can be printed as 'false colour' images with ultraviolet colours converted to colours that we can see
How can we see different colours?
The cone-shaped cells in the eyes detect colours.
How we see different colours?
The cone-shaped cells in the eyes detect colours.
How are the wavelength of visible light seen?
In your eyes are two groups of light detecting sensors at the Retina. Cones detect colour and rods detect light. The Cones are further divided into sensors for three different colours, (red, blue, and green) but their colour sensitivities overlap, so we see our full colour spectrum.The Rods are much more sensitive than the cones, but only detect the presence of light. That is why generally you cannot determine colours at night.
Do proximity sensors help keep my home safe at night?
No. Proximity sensors are generally used to detect objects, not people. Motion sensors use a different technology.
What are light sensors used for?
Light sensors are devices that are designed to detect light. There are several different types and styles of light sensors, each of them unique and having their own specific and useful uses.
Do they have machines that can detect Motion Sensors?
No. There are not machines that can detect motion sensors. You may be able to detect the sensor rays through special lighting, but the beams are normally invisible.
How do you use front camera of iphone 3gs?
Iphone 3gs has no front camera. Those are sensors, an ambient light sensor to detect the light in a room and adjust screen brightness, and another sensor to detect your face during a call to turn off the screen so you don't press buttons on a call.
Does the White House have sensors that detect underground objects what type of sensors are they?
yes
How sensors are used?
Sensors are used to detect things, such as motion, light, or color.
What is a system sensor?
There are many different types of system sensors. These can detect anything from heat, fire, dust, and smoke. There are many different manufacturers as well.
