but I'm fairly concerned that Logan is color blind. He has learned so many concepts with ease, that I may be expecting too much of him. He speaks very clearly in complete sentences (all day long), can name his shapes, animals, numbers, and even recognize some small sight words. He shows no promise of recognizing his colors though.
When did your kids learn colors?

That's a valid concern. I think colors were one of the first things my boys picked up on. Maybe try giving him colored things to group together and see if he can match them up as being the same. Might give a clue as to whether he even sees a difference.
They learned it before Logan did. You were probably nine months, and john's first audible words were pink blankey, which of course was the infamous pink bunny blanket he adopted from your left over blanket abundance...
Owen is still getting black and brown mixed up. I guess sometimes they are kinda close.
He might still be too young to get the colors all straight, though I'm not sure. I thought for a while that Julia might have a little bit of color blindness. She had a hard time distinguishing orange, yellow, red and pink for a long time. She still doesn't know the difference between red and pink. Mark and I argue with each other about color distinctions all the time. I group certain colors with blue and Mark groups them with green. give him a little more time. You might be right though.
Adam didn't really learn his colors until he was about 3. For some reason, it was just a concept that didn't click with him. Alex is starting to identify a few (he's just over 2). I wonder when is the "norm."
My sons learned very early, but don't worry too much yet. I like the idea of putting things in color groups. That could help you decide if he really has trouble--especially in the most common red/green.
My sister was sure her grandson was color blind because he always said the wrong names for colors, but now he seems to do just fine.
Logan is doing so well in other, important ways. Just wait.
Last year I took a Cognitive Psychology course where we discussed color blindness as well as the other types of visual perception problems for several weeks. I'm sure you are already aware of this but there are four different types of color blindness. The three most common are Protonopia (affects 4/100 males, 1/100 females), Deuteranopia (affects 4/100 males, 1/100 females), and Tritanopia (affects 1/20,000). The fourth called Monochromatism only affects one in a million. (I gave you all of the clinical names so you can Google them to get a better understanding of each of them) Also, almost all colorblindness is hereditary in some way or another so if neither Topher’s or your family have a history of it the it’s probable that he doesn’t either.
All of these are rather easily testable once we are older and can understand numbers, shapes and so on but obviously more difficult to diagnose in young children. What Kakes suggests would be a very effective way to figure out if he has one of the third or fourth forms of colorblindness but would not help if he has the first two.
One of the simplest things I've found to test colorblindness and what we talked about in class is "Ishihara’s Test for Color Deficiencies" which you might have Googled already. It consists of numbers made from dots hidden among other dots. I have a PDF with the full test that I could email you if you would like to give it to Logan. Since he already knows his numbers he might be able to take the test. The PDF also has deeper explanations of what colorblindness physically is. Just a thought. Let me know if you want me to email the PDF to you and to what email address and I hope all is well.
Man, I didn't realize I wrote such a novel. Sorry Lisa but hope it helps a little.
Lisa- Jack knows some, but not all. And it's hit or miss on if he'll get them right. He'll ALWAYS answer "blue" when I ask him what color something is. I think each kid has their own timetable on when things will click for them. But, I think it's good that you're paying attention to this so you can keep an eye on him.
I hope things are going well with you; we miss you in the ward. Jack misses his music teacher :(
