Kodi Media Player – How reinforce shade or color of the currently selected button ?

Hello, you can enhance the shading of the MediaPlayer Button under Aeon Nox – this is often difficult to distinguish from the inactive buttons – can you show that in a different color or darker ?

See ScreenShot there is currently selected Play / Pause, which is hardly different from the other buttons

my System : Kodi 16.1 – Raspi 3 – Aeon Nox – LibreElec 7.0
