Who do object appear a certain colour?
An objects colour depends on the wavelengths of light that it reflects
For translucent object, it also depends on which colours they transmit

Absorbs all wavelengths of light, except the colour of the filter itself. This means it will only transmit the desired colour and absorb all other wavelengths
