How do I change color of these icons?

http://yio.co/changecolor.jpg
(I have circled them)

Is there a way to change it using the stylevars or do I have to replace them with new icons?

If so where can I find these icons?
Its hard to see because the icons are as dark as the background.

Please help,
Thanks
