When I read Tim's Sept 18 post that he had checked the blue HP50g against color blindness (Protanopia and Deuteranopia) I ordered one as I have the milder and more common (5% of males) form (Deuteranomaly). I am finding the blue HP50g's keyboard to be the clearest and easiest to read (for me) of any calculator and much easier to read than the standard HP50g keyboard. Some web photos don't do it justice. Many thanks Tim for your colorblind-friendly color choices on the blue HP50g's keyboard.
