Claim One:
1. A method for adjusting chroma and luma values for a video signal, comprising: receiving a matrix of coefficients, which when applied to the chroma values and the luma values of a video signal produces substantially the same result as performing a sequence of discrete operations on the chroma values and the luma values, wherein the sequence of discrete operations includes one or more color-representation conversion operations and one or more processing amplifier operations, wherein at least one of the coefficients is a composite coefficient calculated using at least a combination of the one or more color-representation conversion operations and the one or more processing amplifier operations in the sequence of operations; and for a given pixel of the video signal, performing a matrix multiplication operation between a matrix representation of the chroma values and the luma values for the given pixel, and the matrix of coefficients to produce a modified pixel.
