is made up of different combinations of red, green, and blue light. These three colors, when combined in a variety of ways, can create millions of shades. When colored light is mixed, it's called additive color, because when you combine all of them, you get white.
As you know, film is a photochemical process, and video is photo-electrical. White light is made up of three primary colors: red, green and blue. Different light sources have different proportions of these colors. Our eyes can adjust, but color film and video can’t. Both film and video can only "see" one color of light at a time, and each one has its own way of balancing that light. With color film, you either select tungsten or daylight film, and with video, you use your camera's white balance.
Color temperature is conventionally stated in the unit of absolute temperature, the Kelvin, having the unit symbol K. Color temperatures over 5,000K are called cool colors (bluish white), while lower color temperatures (2,700–3,000 K) are called warm colors (yellowish white through red).
White balance in digital video recording adds tints (opposite the color wheel) to your video as you are recording
Raw Files, record all of the color data—so your white balance (in camera will be irrelevant) and will be done in post-processing
