Because that’s how color was encoded: as high frequencies in the spatial scan. This was conveniently backwards compatible with analog black & white TV, at the expense of color accuracy (which is why the standard was sometimes called “Never Twice Same Color”.)
- IIAOPSW 3y agoLike NTSC/PAL but in a (possibly redundant) basis that is highly optimized by evolution for 3d objects projected down to the 2d retina. Not a rectilinear scanline per se but conceptually similar.
- itronitron 3y agoYes, Margaret Livingstone discusses this in a chapter of the book 'Vision and Art: The Biology of Seeing'. Animals evolved to have black & white vision first and then as color vision evolved the color information was patched onto the black & white signal.
