My 4 year old is almost definitely color blind (I'm a carrier so he had 50% chance and we've done screenings that very clearly indicate he is, but we haven't gotten an official diagnosis.) My youngest son also has a 50% chance but we won't know for a few years. I've read statistics about how common colorblindness is, but I have not met many kids (I'm a teacher) that have color blindness. Or maybe they just never told me...! My father, uncle and grandfather all are colorblind so it is very normal to me and I'm not at all concerned about it but just curious what experience you all have had with color blindness in your family or friends. And I am curious about how understanding his teachers will be in elementary. I don't want them to take points off of an activity if he colors something in the wrong color because they look the same to him.
