Video [[camera operator]]s can white-balance objects that are not white, downplaying the color of the object used for white-balancing. For instance, they can bring more warmth into a picture by white-balancing off something that is light blue, such as faded blue denim; in this way white-balancing can replace a filter or lighting gel when those are not available.

[[Cinematographer]]s do not "white balance" in the same way as video camera operators; they use techniques such as filters, choice of film stock, [[pre-flashing]], and, after shooting, [[color grading]], both by exposure at the labs and also digitally. Cinematographers also work closely with set designers and lighting crews to achieve the desired color effects.<ref>{{Cite book|last=Brown|first=Blain|url=https://books.google.com/books?id=GiQlDwAAQBAJ&q=cinematography+filters+by+color+temperature&pg=PP1|title=Cinematography: Theory and Practice: Image Making for Cinematographers and Directors|date=2016-09-15|publisher=Taylor & Francis|isbn=978-1-317-35927-2|language=en}}</ref>

For artists, most pigments and papers have a cool or warm cast, as the human eye can detect even a minute amount of saturation. Gray mixed with yellow, orange, or red is a "warm gray". Green, blue, or purple create "cool grays". This sense of temperature is the reverse of that of real temperature; bluer is described as "cooler" even though it corresponds to a higher-temperature [[black body]].

[[Lighting designers]] sometimes select [[filter (optics)|filter]]s by color temperature, commonly to match light that is theoretically white. Since fixtures using [[Metal halide lamp|discharge]] type lamps produce a light of a considerably higher color temperature than do [[Incandescent light bulb|tungsten lamps]], using the two in conjunction could potentially produce a stark contrast, so sometimes fixtures with [[High-intensity discharge lamp|HID lamps]], commonly producing light of 6000–7000&nbsp;K, are fitted with 3200&nbsp;K filters to emulate tungsten light. Fixtures with color mixing features or with multiple colors (if including 3200&nbsp;K), are also capable of producing tungsten-like light. Color temperature may also be a factor when selecting [[Electric light|lamps]], since each is likely to have a different color temperature.
