Triple Color Blending Silks

Performer displays three different color silks (say red, yellow and green) tied at one corner.  Two of the silks are held at their free corners, with one silk hanging down like a “Y”

He passes his hand over the silks, and they transform to 3 multicolor silks each colored red, yellow & green.  Silks are freely displayed once again.

If desired effect can be repeated, changing the multicolor silks to three different colors.
