Ophthalmic Endoiluminator (100, 100a, 400), comprising: a light source having only a first monochromatic light source (402) that emits a first light and a second monochromatic light source (404) that emits a second light, the first and second lights defining a light color axis representable in a chromaticity graph (200), the light color axis defining the range of possible colors that can be produced by mixing the light emitted from the first and second light sources ; a collimation element (408, 410) configured to collimate at least one of the first and second lights; a mixing device (412) configured to mix the light emitted from the first and second lights into a single beam of light; a lens (414) configured to focus the single beam of light; an optical fiber (418) configured to transport the single beam of light; and a controller (406) coupled to the first and second monochromatic light sources (402 and 404), the controller (406) being programmed with a control scheme that calculates the appropriate combination of wavelengths of light that must be emitted by the first and second monochromatic light sources, respectively, such that the light color axis intersects a white region (208) in the chromaticity graph, the controller (406) being further configured to: tune the first and second sources of light by altering the intensity of the first and second light sources such that the light produced by the mixing of the first and second light sources represents a point on the color axis of light that is located within the white region ( 208) on the light color axis.Endoiluminador oftálmico (100, 100a, 400), que comprende: una fuente de luz que tiene únicamente una primera fuente de luz monocromática (402) que emite una primera luz y una segunda fuente de luz monocromática (404) que emite una segunda luz, definiendo la primera y segunda luces un eje de color de luz representable en un gráfico de cromaticidad (200), definiendo el eje de color de luz el rango de posibles col
