Thanks for thinking of this. I'm very fond of the use of color to give  
users a sense of place and to help distinguish elements on the page.  
Your question gave me an opportunity to think about the use of color  
in my designs and to do a little research.

Erin probably thought about all of this as she was doing the Uploader  
design but I hadn't really mulled it over before.

The colors are, of course, completely customizable in your  
implementation, they are set via CSS.

However, I would still consider the colors "part of the design". If  
the colors were the *only* indicators or even the dominant indicators  
on the buttons, I would be concerned, but the buttons are clearly  
labeled. The use red and green simply reinforces the meaning of the  
buttons and helps separate them for visual targeting.

You'll see if you run the design through a color blind filter that the  
colors are still quite distinct from each other:;;l=0;j=1;;t=p

Although red and green colorblindness is a fairly prevalent disability  
(occurring in 4 to 8% of males depending on ethnic background), green  
and red are used very widely to indicate go and stop (and various  
other kinds of warning and caution) and following that convention in  
this way seems quite appropriate.
