Color-Coded for Your Convenience with Lucky Seven. Not only is a color motif used, but the specific colors involved are red, orange, yellow, green, blue, indigo and violet. These are often identified as the colors of the rainbow. This trope was started by Isaac Newton, who really wanted there to be exactly seven colors to match the number of musical notes, the number of planets (then) known to be in our solar system, and days of the week. Isaac was wrong about this one, but since he was such a famous scientist, the belief that the visible light spectrum could be separated into exactly seven parts was widely held for a long time. This gave rise to the popular mnemonic "Roy G. Biv", a person's name constructed from the first letter of each color in order. Another mnemonic, more popular in Britain, is "Richard Of York Gave Battle In Vain". Indigo is generally considered the odd man out among the seven, due to it simply being a dark blue.note If the creator needs a few more colors to round out the cast, black and white are common additions. Alternatively, some creators opt to branch out into the non-visible parts of the electromagnetic spectrum, such as infrared and ultraviolet. Curiously, cyan is missing, creating a conspicuous gap between the primaries green and blue, while indigo and violet replace magenta between red and bluenote . For printing inks and finer art, cyan, magenta, and yellow are the primary colors, making orange yet another odd color out along the same lines as indigonote and making cyan's absence even more conspicuous. Example: The Seven Deadly Sins - Wrath, Gluttony, Greed, Envy, Sloth, Lust, Pride often go with red, orange, yellow, green, cyan, blue, and purple respectively. Another way to think of this trope is Chromatic Arrangement plus four extra colors.

Anime & Manga
- The seven types of Dying Will Flame in Katekyo Hitman Reborn!. Each is named after an aspect of weather. Red is storm, orange is sky, yellow is sun, green is lightning, blue is rain, indigo is mist, and violet is cloud. The (orange) Sky Flame is always the leader's flame.
- Each member of the Arcobaleno has a corresponding color, fitting to their Dying Will Flames. The name also doubles as the Italian word for rainbow.
- In Shichinin No Nana, the main character is split into seven of herself, and each girl has a corresponding color. Unlike most cases, indigo is shunted for yellow-green.
- This forms the motif of the seven princesses in Mermaid Melody Pichi Pichi Pitch, with pink, aqua, and deep blue subbing in for red, blue, and indigo, respectively. The second opening of the anime is even called "Rainbow Notes".

- This was parodied in Linkara and Spoony's review of Warrior #4, where they become Gray Lanterns, representing apathy.
- Star Sapphires are more pink (or magenta, maybe) than violet. Because integrating them in the rainbow is actually a retcon.
- The real name of Flash villain Rainbow Raider is Roy G. Bivolo, a reference to the mnemonic.
- Batman and the Outsiders. Halo's super powers each had their own color: heat blasts (red), force blasts (orange), bright light (yellow), a stasis beam (green), mirages (blue), a tractor beam (indigo), and violet (all of the other colors' powers at the same time).

- In The Hog, Carnacki uses rainbow-colored rings of light in his Magitek protective circle, and describes the attractive or repulsive effects associated with each color.

- Ressha Sentai Tokkyuger uses rainbows as a secondary motif (the primary one is trains), combining the franchise's usual color-coding with light vs. darkness symbolism.

- Roy-G-BIV is used as a mnemonic in the rulebook, as the name is in the proper format for a citizen of Alpha Complex (the green-clearance citizen Roy from sector BIV).
