The white point in color definitions is probably one of the least known parameters on a display’s spec sheet. Because what does it even mean? White is white, no? Most people know it is the combination of all wavelengths of light. So how come different settings exist in the market? The reason is that the theoretic value of white is never seen in reality. If you look at a white piece of paper for example, it will be colored by the light source that shines on it. In other words it will look different when you look at it under sunlight conditions, than under artificial light in your office. The same goes for displays. However, the cool thing is that we can often choose the white point of the display. Tampering with the white point setting will consequently impact and define the mood of the image. Note that for convenience we will be talking about displays in this article, but the same goes for just about any visualization device, including projectors and direct view LED tiles.
