"Tabview" Hightlight on Mouseover

https://snippet.webix.com/p9ox7ult
How can we highlight the tab panel on mouse over?
In the sample above when “first” tab is selected, and if the user mouse over the second or third tab, can we highlight these tabs with some color (dark color).
Also needs to change color of the “New Color” button on mouse over!

Thank you.
