This is another data point that might shed an alternative hypothesis to either color blind or not knowing. My daughter knew her common colors well before she turned one, but then when she was a few months into being one, and lasting for many months, maybe from 14 to 20 months old, everything was yellow. It did not matter what it was if you asked her the color it was yellow. She would talk about other colors in conversation, Ie stop lights are red, but if you asked her what color a specific item was..."yellow." Sometimes she knew very well something like a stop sign is red and would get it right, but most of the time,..."Yellow."
This has started a long history of her suddenly not knowing things that she fully knew at a younger age. Although now at 3 she definitely does not hide knowing her colors, she does still do the same thing of completely claiming ignorance of things that she once had mastered. Yes, I know that regression is a warning sign, but I do not think this is true regression, but rather a sort of absolute boredom with material that which she has already learned.
Having read the article Kai's recommended Scientific American article, maybe what happened to my daughter was she learned the easy main colors, then started getting colors wrong that were not easy, and then decided it was easier to call everything yellow. Just speculation.
