Hi Angier,

The FAA only says "contrast in color with the background" but doesn't give 
any particulars.  I think it is up to the DAR or FAA inspector to make that 
call.  We haven't had any problems here putting gray letter on a blue 
background and vise versa.

Cream on a white background probably wouldn't cut it.

If it looks/feels questionable to you then it might be questionable to the 
inspector as well.

I hope this helps.

Have a great day,
