Three primary colors

Oh, there are three primary colors,
Only three are primary as truth
The world is full of every kind of color,
But we're just talking red, yellow and blue.

Red (red, red)
Red (red)
Yellow (yellow, yellow)
Yellow (yellow)
Blue (blue, blue)
Blue (blue)

These three are the primary as true.

Oh, there are three primary colors,
Only three are primary as truth
But if you mix the primaries together
Brand new colors come right into view

Red and yellow make orange (orange)
Yellow and blue make green (green)
Blue and red make purple (purple)
And there's a lot of colors to be seen.

There are three primary colors
And a lot of other colors are there too,
When you see another other color
They're all made up of red, yellow and blue.

Red and yellow make what?
Red and yellow make orange (orange) (right!)
Yellow and blue make what?
Yellow and blue make green (green) (that's right!)
Blue and red make what?
Blue and red make purple (purple) (right!)
And there's a lot of colors to be seen.
