[|Human|] my 18 months old grand child ,who talks a lot, very sensibly and with no grammatical mistakes and has a vocabulary of 389 words , always seems to be making a mistake when it comes to colours. We are wondering if she could be colour blind. Is there some simple way to test that. Thank you.
[|AI|]  Hi...by what you quote I feel that your suspicions might be right. But it is too early for an 18-month-old to identify all colors correctly. It is very simple to test for this. There are charts called iShares charts. There will be a number imprinted and a normal person and a color-blind will read different numbers. But for an 18-month-old kid it is difficult to identify the number. I suggest you get in touch with an ophthalmologist. Regards -
