md-button: href ripple color

[epelc]

If you have a button with an href the ripple color is red. Shouldn't it default to light grey if you don't add any classes to the button?

<md-button href="http://www.google.com/" target="_blank">Google</md-button>

I'm actually seeing the default blue/purple colors for links that get added in place of <md-button>. @epelc, are you using a theme?

Ahh, I am noticing it's the ripple color, not the foreground color. It seems related to the default color issue I mentioned above.

I tried it in my app which uses a modified green theme and on the docs.

I don't see red ripples anywhere in the docs, although I did see them on Codepen (which has a default stylesheet). The "Go to Google" link button in Demos > Button inherits a blue text color from our docs.css, which highlights that a default color is missing from the component itself. I am updating md-button to use color: currentColor in the absence of a theme class. That way it will update based on the body color.

Something to keep in mind is we're adding basic typography support in 0.9.0. So if we want to make changes to this behavior, we can revisit it then. #1128
