* YCbCr colors represent colors as a Y luma brightness component and red and
* blue chroma color offsets. This color representation takes advantage of
* the fact that the human eye is more sensitive to brightness than the color
* in an image. The Cb and Cr components are often compressed and have lower

*
* When the color information in YCbCr is compressed, the Y pixels are left
* at full resolution and each Cr and Cb pixel represents an average of the
* color information in a block of Y pixels. The chroma location determines
* where in that block of pixels the color information is coming from.

* The color range defines how much of the pixel to use when converting a

* entire numeric range of the pixel bits is significant. When narrow color
* range is used, for historical reasons, the pixel uses only a portion of
* the numeric range to represent colors.
