1. A light array, comprising:

  • a plurality of colored light-emitting diode elements dispersed within a light array and configured to provide a uniform color output;

    wherein said plurality of colored light-emitting diode elements comprises six red light-emitting diode elements, six green light-emitting diode elements, six blue light-emitting diode elements and six white light-emitting diode elements, wherein said white light-emitting diode elements each compromise at least one light emitting diode in a structure configured to emit white light;

    wherein said red, green, blue and white light-emitting diode elements are arranged to form a 4×

    6 rectangle in said light array with said red light-emitting diode elements being located towards a center of said light array, wherein said six red light-emitting diodes are grouped in two groups that each compromise three of the red light-emitting diode elements and one of the white light-emitting diode elements to form a central part of said 4×

    6 rectangle that is surrounded by said six blue light-emitting diode elements and said six green light-emitting diode elements and a remaining four of said white light-emitting diode elements, said remaining four of the white light-emitting diode elements being located at each corner of said 4×

    6 rectangle; and

    wherein said 4×

    6 rectangle has a long edge defined by six of the plurality of colored light-emitting diode elements and a short edge defined by four of the plurality of colored light-emitting diode elements.
