Changed my clinic's appointment cards from yellow to white based on a hunch

Swapped the yellow paper we use for appointment cards to plain white at our office in Tacoma last month. Within two weeks, three patients older than 70 said they could finally read the date without needing a magnifying glass. Hadn't realized how much that yellow was washing out the black ink for aging eyes.

Gotta disagree with you here. I worked in a print shop for 12 years and yellow paper with black ink is actually proven to be the most readable combo for people with low vision and certain eye conditions. There's a whole science behind it called contrast sensitivity. The problem might be that your specific yellow was too pale or your black ink too thin, not the color itself. Swapping to white might help some folks but it's going to make things worse for others who rely on that yellow contrast to reduce glare and eye strain. I'd keep both options available if I were you.
