Can you please bring the icons back with colour?

I have spent some time now using 2016 and I must say it is not nice to use.

After working all day with it I am ending up with aching eyes and that means the interface is not good.

With the icons being the same colour and even worse using different icons than 2015, its a pain.

Rotate view is a different icon for example.

Looks like an old AutoCAD interface!

Sorry! :-(
