(I'm a regular, but have name-changed as this is a bit unusual and I don't want to "out" myself )
We are almost certain that DD is colour blind - there is a family history and she always calls red "green" despite being really sound on all her other colours/numbers/animals etc. This is fine - after all we know that other people in the family have coped just fine with being colour blind. The only problem that we have is that we don't know what to do when DD gets the colour "wrong". She's obviously learned the colour green first, and as far as she's concerned that's the name for both green and red as they're the same colour for her. We tell her that things like fire engines and tomatoes are red, because she will need that knowledge as she grows up. Should we tell her about other things too though? If she asks for the green pencil then I tend to let it slide and just give her the red pencil. She has started getting very reluctant to discuss colours when the answer is green or red, as she gets it wrong so often. My Dad seems to be able to distinguish between red and green quite often though due to very subtle differences, and if we can teach her that, then obviously we'd like to.
Is anyone else dealing with this, and what do you do? Is there any official advice about dealing with a colour blind child.
