tabs: tab label text and inkbar colors not aligned with spec

Based on the spec, they show tabs on a white background having the indicator the same color as the text and primary color:

The current md-tabs shows the indicator as the accent color on a white background:

To make matters more complex, in the spec, the accent color is used when the theme background is non-white (or is the primary color)

I'm not sure if this can be easily fixed or if it will cause some theme inheritance problems. If so, perhaps md-tabs should be able to take md-theme ? Or does this just have to do with light theme vs. dark theme?

In fact reading the spec, it also shows an example where it states:
"Text color is the same as the tab indicator"

while in details below

Indicator:
"Height: 2dp"
"Color: #fff or accent color"

Tabs with text only

Text
14sp Roboto Medium
Active color: #fff or accent color
Unfocused tab color: #fff 70%

Reading this, it looks to me that the typical option is to use accent color for both the text and the indicator.

Do I read this incorrectly or is there an inconsistency?

Definitely need to take a look and see if it still lines up with the spec. Perhaps something changed and we haven't updated styles accordingly.

The spec does seem to contradict itself. I've seen in many google apps using the same primary color for both the indicator and the text, so long as the background is white/grey.

Either way, perhaps md-tabs can take the class md-primary and we can leave it up to the developer.
