This video is great at showing non-colorblind people what some colorblind see. The woman’s son is colorblind, so she does a little interview with him, to ask him how he picks out certain colors. They also take some pictures and run them through a filter that demonstrates how he sees - to a non-colorblind person, the difference is obvious, but he struggles to tell the difference, indicating the filter does a good job of showing what he sees.
