For a graph G, let χ(G) denote the chromatic number and Δ(G) the maximum degree of G. The list coloring number ch(G) satisfies the following properties. ch(G) ≥ χ(G). A k-list-colorable graph must in particular have a list coloring when every vertex is assigned the same list of k colors, which corresponds to a usual k-coloring.
A 2.26 kΩ, 1%-precision resistor with 5 color bands (), from top, 2-2-6-1-1; the last two brown bands indicate the multiplier (×10) and the tolerance (1%).. An electronic color code or electronic colour code (see spelling differences) is used to indicate the values or ratings of electronic components, usually for resistors, but also for capacitors, inductors, diodes and others.
A mnemonic which includes color name (s) generally reduces the chances of confusing black and brown.

The color e-paper offerings of the same era just couldn't compete -- Kyobo's $310 Mirasol eReader was panned for having poor battery life and unstable software, and an E Ink Triton device by ...
Data visualization refers to the techniques used to communicate data or information by encoding it as visual objects (e.g., points, lines, or bars) contained in graphics. The goal is to communicate information clearly and efficiently to users. It is one of the steps in data analysis or data science. According to Vitaly Friedman (2008) the "main ...
Gallery 3’s CMYK displays can spit out 50,000 colors at 300 DPI — way, way up from Kaleido’s 4,000 colors, the company said. A prototype with E Ink’s Gallery 3 display tech. Image Credits ...
Electronic paper. Many e-readers, devices meant to replace traditional books, utilize electronic paper for their displays in order to further resemble paper books; one such example is the Kindle series by Amazon. Electronic paper or intelligent paper, is a display device that mimics the appearance of ordinary ink on paper. [1]
25-pair color code chart used in certain kinds of wiring. A color code is a system for encoding and representing non-color information with colors to facilitate communication. This information tends to be categorical (representing unordered/qualitative categories) though may also be sequential (representing an ordered/quantitative variable).
