: [[Colour]] exists because [[object]]s filters work by [[Absorb (Physics)|absorbabsorbing]] some [[frequency|frequencies]] of [[light]] while other [[colour]]s are not.: A [[colourtransmit]]ed [[object]] [[Absorb (Physics)|absorbs]] some [[colour]]s and [[reflect]]s ting others. For example [[leaf|leaves]] are green because the [[chlorophyll]] inside them [[Absorb (Physics)|absorbs]] red and blue [[light]] but not [[green]].
===Eyes and Colour===
: White can be made by mixing red, blue and green [[light]].

: [[Colour]] filters work by [[Absorb (Physics)|absorbing]] some [[frequency|frequencies]] of [[light]] while [[transmit]]ting others.
: Looking through a [[colour]] filter makes any [[object]] whose [[colour]] is [[Absorb (Physics)|absorbed]] appear black.
