Colour contrast on logos

Hello,

I have been doing some accessibility testing on a website with a view to
achieving WAI AA compliance. Obviously that has included analysing the
colour contrast of text and background and all of the actual text now
has sufficient contrast. What I'm not sure about though is how this
guideline applies to logos? We have a new logo which is used on the page
in a couple of places as a gif image. The logo is basically some text in
a pale green on a white background - not a sufficient contrast for text
by any measure but as this is a logo does it matter? I can add title and
alt attributes to the image but is this sufficient for compliance
purposes or should we really go back to the designer and request a more
accessible logo?

I look forward to your comments.

Many Thanks
