Nearest color algorithm using Hex Triplet

Wikipedia has a list of colors that I am using for a basis of color names. I want to find the nearest named color given an arbitrary RGB value.

Graduated transition from Green – Yellow – Red

I am having algorithm mental block in designing a way to transition from Green to Red, as smoothly as possible with a, potentially, unknown length of time to transition.

How is a 256 bin HSV histogram quantised?

I am doing some research on the ScalableColor descriptor in MPEG-7 and I came across this passage:

What algorithms are there for picking colors for plot lines on graphs?

I’m interested in what algorithms or rules I can programmatically implement to generate RGB or HSV colors for plotlines to keep them visually distinct from the neighbors.

There are two types of color mixing: Additive and Subtractive. How about XOR-ive color? [closed]

When is it appropriate to use colour in a command-line application?

Currently I have a command-line application in C called btcwatch. It has a -C option that it can receive as an argument that compares the current price of Bitcoin with a price that was stored beforehand with -S. Example output with this option is:

Why are background-colors not or rarely used for syntax highlighting? [closed]
