YUYV

In the world of color, there's a model called YUV, Used in TVs and computers too, it's true. Y is for luma, the brightness we see, U and V are for chroma, as happy as can be. Y′ is the luma, calculated from RGB, Different from true luminance, you see. U and V are the chroma components two, They make colors pop, in a vibrant hue. In the olden days, when TVs were black and white, U and V were added, what a sight! A subcarrier made it possible, oh so clever, To show color on screens, and make us all endeavor. Y, Y′, U, and V, not abbreviations they be, But chosen letters with a special decree. Y for luminance, from XYZ it came, Luma Y′, a correlate of luminance, the same. U and V were picked to stand out, Different from other spaces, without a doubt. So remember the YUV model, it's quite grand, With luma and chroma, color at your command.
