Flowing in waves but straight waves unseen by eyes. A transparent piece of glass can slice it into a million colours and a trillion shades. And the colours continue flowing in many more waves and straight waves. Poetry flows with them. Songs have been forever sung. Feelings and passions swirl and twirl within the many shades. Cold or regal or stable ! Blood or fire or love ! Colours make the world a beautiful place. Black and white pictures are just that, black and white and unreal.
