Change Corona light color according to time (Animation)

[CBAS VISUAL]

Hi guys,
We are doing a video and need to animate light color
I know I can change a Corona Light Material Color but I yould really rather have the all lighting system to change color instead
I thought about having two Lights with diffrent colors and dime the first one while increasing the other one’s value.
But is  there an easier way to keyframe a CoronaLight Color for example ?
 
Thanks in advance

You could perhaps composite the individual passes in after effects and animate colour by changing the layer colours.

Not sure about the question here - if using a Corona Light, and you enable Auto Key, you can just go to the frame and change the Corona Light color, and a key is recorded. Was it something else you were asking about though? e.g. I don't know what you mean by "the all lighting system")

You can set up a very simple Xpresso Setup with less than a dozen nodes.
There's one dedicated node for changing frames/forgot the name. That should be useful.

edit: quick setup. You should get the gist for other things, like a dependency of light A to B, controlling some aspect of the light. etc pp
