Red/Green ColorBlind Toddler?

Question:

My son is nearly 3 and he is above average in most things like numbers, letters etc. However, he knows all his colors but can not seem to tell the difference between red and green at all. Everything red is green to him. I should add that my own grandfather had red/green color blindness and it was only detected when he tried to join the Navy in WWII when he was 25. The other thing I wonder about is if he is, when he sees grass - how does that appear to him if color blind? Any thoughts, opinions etc, much appreciated.
Thanks

Answers:
I didn't know I was Red Green Color-Blind until I joined the Army. The way it works is when the colors are close together they blend. For example if a traffic light was lit up at the same time green and red I would not be able to tell which color was which. But since they are occuring at seperate times they are distinct then.
The grass should look green.

my dad had the same thing but green/yellow everything yellow looked green and everything green looked grey. try asking him how it looks.

he could be color blind and it could just be that he likes the color green or likes to say green. My granddaughter likes to tell us that every thing is orange even when she knowns it 's not. You need to remember that a child's mind is always working and that their perception is not always that of an adult . When my son was that age he colored everything black and when asked what his favorite color was he would say black. When his aunt told him that black was not a color it was an opaque blah blah blah. He looked at her and said then why is it in my box of crayons. If you are real worried I would talk to my Doc about it and see what he says .
