Artistic use of black and white photography is often used to convey age and historical differences. An example of black and white photography in a film is the 1993 Steven Spielberg film "Schindler's List."
By combining props of the same color in the same scene, a director can often influence a certain mood in the viewer. An example of this is by using the color blue to convey loneliness and depression. Krzysztof Kieślowski often used this effect in his 1993 film "Three Colors: Blue."
Some films use painted effects in real life situations to give a sense of fantasy or unrealistic goals. This may include the painting of flowers in a impressionist fashion while leaving the rest of a shot unchanged. Danny Boyle uses this same effect in his 2002 film "28 Days Later."
Desaturated color is often used to convey poverty or age. In this effect, the brilliance of colors is dulled and darker colors (gray, black, brown) are used. Sam Mendes uses this effect heavily in his 2001 film "Road to Perdition."
Saturated colors can be used to accent a particular scene or object. When a color is saturated, it is made more brilliant or brighter. This effect can be achieved from digital effects or colored light cast on an image from off screen. An example of this technique is the Ethan Coen film "Blood Simple."
