Hey guys, thanks for all the great work!

I am trying to set up a core-scroll-header-panel with a background image 
for #headerBg and a background-color for #condensedHeaderBg like in Rob 
Dodson's I/O-14 demo, but get stuck with defining text colors. 

The problems is that you are typically choosing a contrasting color for 
text sitting on top of a background-image within the header panel, but when 
you add a background color that appears when users scroll down and the 
background images fades away, you would probably often want that background 
color to be contrasting to the background image as well, which would make 
the text unreadable.

So, I would probably need a method to add a color property to 
#core_sroll_header_panel whenever #condensedHeaderBg is triggered by the 
scroll event. Would that be feasible somehow?
