Component is interesting, You would expect that the three colors would be blue, red and green, the three primary colors in light and TV, tho the red is actually an orange-red plug, to make it different from the familiar audio red. The blue and reddish plugs are chroma, or color. Blue is blue chroma and red is red chroma. Oddly, the green terminal is not chroma, or the green color level, but luma, the overall brightness of the picture. Since we know the overall brightness of the picture the green level is also known as it is simply determined by the subtraction of the red and blue from the total luma brightness. What remains of the luma that is not red or blue has to be the green in the picture.
Disconnect the green luma and the resulting TV picture will be totally black. Swap the red and blue and the red and blue in the picture will be swapped.
The latest trick on the new TVs is to not include a separate yellow composite video input. The green luma plug can also be used as a composite video input, so it is marked half green and half yellow.
