I'm sorry but every camera on the planet except the 500 has a decent 5600 preset so don't act like its a special feature. Thats just ridiculous.

5600k is black body radiation at specific frequency and not just some arbitrary thing like you seem to think it is.
You may argue with Lord Kelvin about that but I don't think you'll get an answer. He's dead. BTW he's the K in 5600k.

Making it sound like I want something special is particularly silly when you could look it up in any high school physics book
or even google color temperature.

But the real problem here is color cast. What you want any camera to do is to provide presets the look reasonably close to what your eye sees in the same situation.
Most cameras can do this especially outside. Having a gorgeous blue sky render yellow-green is not even close to what the eye sees and this is what the 500 does. You can see it on scopes and you can see it with your eyes.
Why it does it I don't know but it does it.
But I'm still left with the nagging feeling that it isn't a mistake but something that was done to enhance some other part of the cameras performance.
Maybe the reason it took so long fix is it was hard to do it without breaking something else.
The fact that its in the yellow green part of the spectrum is interesting. Especially since that carries the luminance info.
Perhaps too high a voltage to all the green pixels?
Who knows. Maybe you should have just used an daylight filter in the filter wheel.

On another matter I'm not sure why I should be fiscally punished for your mistake. As I said before all I did was buy the camera. You built it and sent it out with a problem.
If you really cared about your customers you'd pick up the shipping to fix a problem like this. But obviously you don't.
Good luck in your future endeavors as this will assuredly be the last Panasonic camera I buy for a long, long, time.
