Robin- I think it would be very rare that Lela is color blind as well. Beyond the blue/green thing you have.

BTW: Great explaination tweety.

I think colors can be hard to teach and some kids pick up on one thing easy and other things not so easy.

In our playgroup it seems 50% of the kids by 24 months know their colors. There are many toys you can test & teach color with. The best I have found is something where the item is the same over & over and just the color changes.

Mason has a puzzle of solid color fish from Melissa & Doug and you have to put the corect fish with the correct color. Mason doesn't say all his colors yet but he always matches them up correctly in this puzzle. Discovery toys makes a toy where it has different color balls to match up to holes and if they mix blue & purple up it is usually an early sign.

Try any learning store for color teaching toys. Mason also has an ice cream cone set that all the scoops of ice cream are different colors and I teach him them like that too.

Now I have to check out that test you posted
