Dashboard Feature Request (Batttery level tiles)

I have a feature request for Dashboard 2.0.

I currently have a Dashboard with all of my battery devices with their current battery levels. The dashboard defaults to bright green. When I look at it the dashboard on my mobile device and my poor eyesight (LOL), the numbers blend in.

I would like to see configurable battery tile colors based on battery percentage. For example: Green > 70 %, Yellow > 50 and <70, and red < 50. Or something like that.

This way, a visual glance at the dashboard could let a user know when the battery levels are getting low.

Anyways, just a thought. Don't know how hard it would be to do or if was even doable under current programming setup.
