dc is 3 and a bit. talks well never shuts up and likes painting/colouring. seems to mix up blue and green quite a bit, not when painting (still at the messy crissycrossy stage) but when talking. will guess when I show a pen/object and ask what colour it is. is that still normal for that age or should I go to an optician?
We had this with DS last year (he was 3 at the time)I checked with the optician who gave him a full eye test, including colour blindness check and all was fine. He had a follow up six months later and no change - all still ok.
Optician said he was probably just getting colours confused.
My DD is 3 in a few wks & used to do this. Now she confuses yellow & red .
Its red & green that are the 2 colours that cannot be distinguished in the most comment type of colour blindness. If you're still concerned, you can find colour blindness images online. Just Google colour-blindness animal tests or similar. As long as your DS knows his animals, that should work
