Blue is my favorite color. Blue is one of three primary colors.
I like red more, But the blue is good too, My boyfriend has blue eyes.
I have green eyes. Eye color is determined by phenotypes.
Yes, and the blue eyes and green are rare, gen for brown eyes are more often. 
The part of the eye that actually shows the color is called the iris.
My iris is brown, some people say that lighter eyes have worse vision then brown.
I have never heard that before. There is also a plant called an iris and it has showy flowers.
Yes, I know, it is a beautiful flower. But my favorite is rose, Red Rose actually.
My favorite flower is a hydrangea. They are native to southern and eastern Asia.
I have never heard of that flower, but it must be very beautiful.
