The point about contrast is enabling people to see things. If the logo is  
textual, but too low contrast to read, the odds are that it is too low  
contrast to be recognisable in any case, which means it isn't doing its  
job as a logo. (Note that contrast is higher priority for images than for  
text, since in principle you can more easily change it for text).

So yes, I would be going back to the designer, pointing out that  
recognition by everyone is a requirement for the design and low contrast  
washouts aren't going to meet that requirement...

(This is based on my imagining the design, which is of course not  
reliable. Please check my arguments with your perception of reality. Your  
mileage may vary :)
