Blue, Yellow

It is an interesting thing attempting to teach toddlers colors. I have become, suddenly, keenly aware of the colors of everything and use the color as a descriptive. "Here is your blue cup, your red shirt, your green hat," etc. I now fully understand why all the Sesame Street and Barney characters are very specific colors. "This cup is yellow like Big Bird."
Interestingly, if you ask the boys what color anything is you always get the same answers. Chase always say blue, Ryder always says yellow.
Just recently, however, Chase has been saying orange when, amazingly, things are orange. It remains to be inconsistent.
I like to test them. I will ask what color something is, say an apple, get their standard answers (blue or yellow) then follow up with the correct answer. Then, ask further, what else is red? Elmo, a fire engine. Someday, they will be able to answer all of these questions correctly, but first, they must learn their colors.
