An LED lighting fixture includes a housing; a substrate located within the housing; a plurality of LED groups of various colors mounted on the substrate, each LED color group including multiple LED components; at least one circuit communicating with a power supply and adapted for powering the LED components; and an optical component located at an output end of the housing. The LED components are arranged along first and second directions orthogonal to one another, such that no two LED of the same color reside adjacent one another along both of the first and second directions, and each LED component is spaced-apart from an adjacent LED component a distance no greater than 1.0 mm.
