Component have more accurate color than S-video by breaking down color information even further than S-video.
The only similarity between component and s-video is that they both carry luma (black&while/resolution) information separate from chroma (color) information. And that is where the similarity end.
The difference begin where in s-video, color information is carried in one wire. But in component, the color information is broke down in two wires where blue cable carry difference between blue and luma, and red cable carry difference between red and luma. Green cable only carry Luma information.
A green color is not sent as the color can be interpolated using the blue, red and luma information. This is done to save bandwidth.
