The museum gift shop display taught me more than the exhibit did
Last month I went to the natural history museum in Portland with my nephew. The exhibits were great, but I kept staring at their interactive touch screen guide. The labels had this pale yellow text on a white background, and I could barely read it under the overhead lights. My nephew, who's 9, read it fine. I had to squint and turn my phone flashlight on it just to pick an exhibit. That made me realize contrast isn't just about WCAG numbers. It's about real lighting conditions, glare, and older eyes. After that I started testing my own design mockups on my phone outside, in a dim room, and even on a cheap monitor at max brightness. Has anyone else run into a public display or sign that looked fine in theory but fell apart in the actual environment?
