The older I get, the more my eyes complain that they are past 40 now. I'm having more trouble reading on the screen these days than I did ten or even five years ago, and somehow I suspect it is not going to get better (lol).

Thus, I've become more sensitive to readability issues in regards to font size. There are two instances in particular where designers really should pay more attention to accessibilty:

At first glance, WellStyled.com's Color Scheme Generator 2 [EN] seems to be just another useful web design color palette tool. But this tool includes an extra accessibility feature. The pulldown menu on the bottom right will adjust the selected color palette to demonstrate how the color scheme will display given various degrees of color blindness.
