Tabbed navigation designs and 1.4

Take a look at this website:

http://www.rnib.org.uk/xpedio/groups/public/documents/code/public_rnib003460.hcsp

These tabbed navigation designs are quite common on a lot of websites. The
first row of links are "tabs" and the second row is a sub-menu of the
selected tab. The selected tab and its sub-menu are associated through
presentation (color). ARIA will provide a way to programmatically expose
this relationship conveyed through presentation (1.3).

But what about 1.4? Color is the only "visual" means of conveying which tab
is selected. But is this a problem for someone with color vision deficits?
The particular color is not relevant. It's the contrast between the light
color (yellow) and the dark color (red) that the user needs to be able to
detect.

Would this example fail 1.4? Should it?
