how we see color
Most materials absorb some frequencies of light and reflect the rest. If a color is absorbed, it is NOT seen. If a color is reflected it IS seen. Therefore, the color you see is the color being reflected by an object.
The three primary colors of light: Red, Green, Blue
If all colors of light are reflected, the object will appear white.
If all colors of light are absorbed, the object will appear black.
The color we see depends on:
An object that appears Red- reflects the red wavelength and absorbs the rest

The color we see depends on:
- The color of light that is shined on the object
- The color of light that is reflected by the object

color filters
Color filters only allow certain frequencies/wavelengths of light to pass through, they absorb or reflect the rest.
A color filter that transmits the frequency of blue light means that when blue light passes through the filter, it looks blue. However, if a different frequency of light passes through the filter it will appear black because the frequency is absorbed or reflected.
(Blue filter--Blue light--Appears blue)
(Blue filter--Red light--Appears black) *This would be true for all colors except blue
