Edge‐colorings avoiding rainbow stars
Journal of Graph Theory, 2017AbstractWe 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 of Bubble Sort Graphs
Communications in Computer and Information Science, 2019There are many kinds of edge colorings. This paper deals with a special edge coloring named rainbow coloring. Different from other edge colorings, the rainbow coloring requires every pair of vertices has a rainbow path between them. A rainbow path is a path \( \, P \, \) in graph \( \, G \, \) such that every edge on P has different color.

Color blur of the rainbow hologram
Applied Optics, 1978The 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.

Colored Saturation Parameters for Rainbow Subgraphs
Journal of Graph Theory, 2017AbstractInspired 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

What are “all the colors of the rainbow”?
Applied Optics, 1991Both folklore and theory imply that naturally occurring rainbows display a wide range of nearly pure colors. However, digital image analysis of color slides shows that the natural rainbow's colors are not especially pure and that the bow's background causes much of this desaturation.

A Two-and-a-Half Color Rainbow
Archives of Neurology, 1994I heldup a tablet from my breakfast plate and asked Marilyn what it was. "A new brand of vitamin," she replied. I commented that the drug firm should fire their marketing staff for putting a black vitamin pill on the market. She glanced at me, "It's not black, it's dark red." The instruction on the handle of my weed eater says in yellow print, "Before

Rethinking the Rainbow’s Colors
Light and Color in the Open Air, 1990For 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.
