The YIQ color space is used in U.S. color television broadcasting. Conversion from RGBA to YIQA may be accomplished using the color matrix:

Y \\
I \\
Q \\
R \\
G \\
B \\

(Generally, YIQ is not used with an alpha channel so the fourth component is eliminated.) The inverse matrix is used to map YIQ to RGBA [30].
