The enhancement of the intrinsic viewing screen brightness of the Mosaic Additive system of color reproduction, sufficient for saturated reflectance color displays to be viewed comfortably by the ambient light, is taught. The enhancement comprises three means which may be employed severally or in combinations, to wit: I. Photoluminescent compositions in the color elements. II. Juxtaposed subtractive primaries with the additive primaries, as color elements. III. Variable (optical) density interstices. It is within the contemplation of the invention to effect an image, in cooperation with the viewing screen of this invention, by any suitable mechanical, electrical and/or chemical impression technique where it is desired to produce a Mosaic Additive color image for viewing with the unaided normal human eye by reflected ambient light. Such uses include: reflectance color-Television, Printing, Facsimile, Photography, and Xerography. The invention also specifies adaptations, of otherwise black and white embodiments of these reflectance imaging means, to color.
