What is your favourite colour? Mine is purple. It is an intermediate colour between blue and red.
Mine is blue!  I have a lot of clothes that are blue!
Blue is good. It is one of the primary colours.
What do you mean primary?
Primary colours are any of a group of colours from which all other colours can be obtained by mixing.
Oh.  I think I sort of remember that from school.  What did the intermediate mean that you stated before?
It means on the traditional colour wheel used by painters, it is the inbetween colour between red and blue.
