White guitars show up on a TV. You guys don’t know what you are talking about.
I have a degree in Television Broadcasting and have worked as a TV reporter for a number of years.
white is fine.
In fact you hold up a piece if white paper in front of the camera to do something called a”white balance” before shooting to make sure all the white is picked up correctly.
You see white on TV every day.
what you can NOT have on TV is thin, black and white lines close together. Then you have problems.
But plain white is absolutely fine and always has been.
