The unweighted color reproduction is not only due to the camera. I have made two screenshots, both with the same color control position but with changed brightness. You can see that the yellow bar is darker in comparison to cyan with lower brightness, but it is brighter than cyan with high brightness.
These old color tv sets do not provide a full contrast range which is necessary for correct displaying the colors. So, people usually watch tv with low contrast and brightness, but high color control setting. Since the color green is computed in the dematrix circuit out of I and Q and Y, the green (and also the yellow) will be much darker in comparison to other colors with reduced brightness, which is a reduced Y. You have to adjust a correct contrast-rich black and white picture before you add color.
Is this correct?
Kind regards,
