I love the color blue.
Yeah, me too! It's quite nice being one of the three primary color pigments. 
And when mixed with red it is amazing that it makes purple.
Yes! Purple is similar to violet, but unlike it also. There are lots of composite colors. Do you ever do any painting? 
Yes from time to time. Do you know what color orange mixes with to make brown?
I don't! I do know that orange used to be a symbol of protest against the human rights violations in China though. What color does it mix with to make brown?
Well I think now that it is actually yellow and orange that make brown. Colors are so fascinating.
It is! In the middle ages, blue was used when making the windows of Cathedrals.
