Color rainbow hologram and color reproduction

Applied Optics, 1988
A new method that uses color separation and an achromatic holographic stereogram to reconstruct a natural color image is proposed and described. Three primaries for tone reproduction are decided by the relative spectral distribution of a reconstructed image from a bleached hologram illuminated by a halogen lamp.

Edge‐colorings avoiding rainbow stars

Journal of Graph Theory, 2017
AbstractWe consider an extremal problem motivated by a article of Balogh [J. Balogh, A remark on the number of edge colorings of graphs, European Journal of Combinatorics 27, 2006, 565–573], who considered edge‐colorings of graphs avoiding fixed subgraphs with a prescribed coloring.

Rainbow coloring the cube

Journal of Graph Theory, 1993
AbstractWe prove that for d ≥ 4, d ≠ 5, the edges of the d‐dimensional cube can be colored by d colors so that all quadrangles have four distinct colors. © 1993 John Wiley & Sons, Inc.

Rainbow Color Map (Still) Considered Harmful

IEEE Computer Graphics and Applications, 2007
In this article, we reiterate the characteristics that make the rainbow color map a poor choice, provide examples that clearly illustrate these deficiencies even on simple data sets, and recommend better color maps for several categories of display.

Colored Saturation Parameters for Rainbow Subgraphs

Journal of Graph Theory, 2017
AbstractInspired by a 1987 result of Hanson and Toft [Edge‐colored saturated graphs, J Graph Theory 11 (1987), 191–196] and several recent results, we consider the following saturation problem for edge‐colored graphs. An edge‐coloring of a graph F is rainbow if every edge of F receives a different color. Let denote the set of rainbow‐colored copies of

Rethinking the Rainbow’s Colors

Light and Color in the Open Air, 1990
For most of us, the phrase "all the colors of the rainbow" conjures an image of the natural rainbow1 as a paragon of color variety and vividness. Indeed, both our language and art often invoke the rainbow as a color palette without peer.2 Yet as a color standard, the rainbow has an oddly contentious history.

Color blur of the rainbow hologram

Applied Optics, 1978
The color blur of the rainbow hologram is calculated from first-order holographic theory. The result is applicable to most of the rainbow holographic processes, including the one-step recording technique. Horizontal color blur approaches zero if the rainbow hologram image is near the optical axis of the hologram aperture.

Color evaluation of computer-generated color rainbow holography

Journal of Optics, 2012
A color evaluation approach for computer-generated color rainbow holography (CGCRH) is presented. Firstly, the relationship between color quantities of a computer display and a color computer-generated holography (CCGH) colorimetric system is discussed based on color matching theory. An isochromatic transfer relationship of color quantity and amplitude
