I am designing a mobile app On which color theme will depend upon Device theme. 

I am using mobile version of tau.js.

Initialy I have used  " data-type="colored" " which takes the default color. But now 

I want to take colors from tau as per device theme.

Can anyone suggest , How can I do it ??

Besides Can anyone help with any sort of documentation or guide over tau ?

Thanks in Advance
