Is it possible to change the background colour of notifications in android lollipop.

I noticed that some notifications are white, some light grey and some are dark grey.

You can see the music player notification has a dark grey background. and in the second screenshot some are light grey.

How do I set this colour? And is it possible to completely change the colour e.g. any hex code. Or can you select them from a template such as material dark material light.

Thanks for taking the time to answer
