Learning Colors

My (almost) two year old has been working on her colors. Here's a conversation we had some time ago while on a walk:

Me: What color is that car?

Daughter: Blue!

Me: Hmmm... actually it's red. What color is the grass?

Daughter: Blue!

Me: mmm... actually the grass is green.

Daughter: Grass... green!

Me: Exactly. What color is that house?

Daughter: House... blue!

Me: mmm... well, the house is white.

A brief pause. We both look around.

Me: Ok, what color are papa's jeans?

Daughter: blue!

Me (in my best praising voice): Exactly! Very good!

She's getting better.
