Looking at another Matisse collage.  Look the horse – a bluish Red in color, with a bluish Yellow line running through it.

These are complementary colors, or at least, they are moving towards being complementary colors.

As we see from the color circle, these two colors start as near opposites, thus, complementary colors.  They are moving in the same direction, and so they are moving together.  It is a long way to go, so the connection is not as intense as with the Full Inversion, but the connection is there.

The chart shows clearly the movement of the colors towards each other.
