Four hands are coming together in unity and at the same time diversity. Hands are a symbol for action, greeting and welcoming. A handshake is an agreement to work together. Holding hands is an expression of love.
The four primary colored hands weave into each other, mixing and, through transparency, creating new colors and by intersection heart like shapes.
In order to achieve anything in this world, we have to work together with compassion, understanding, tolerance and in the spirit of collaboration and cooperation.
