1/*!
2This module implements all terminal color rendering operations,
3color conversions, color name definitions and traits for rust color library.
4
5### 3bit and 4bit
6
7The original specification only had 8 colors. The **SGR** parameters 30-37 selects
8the foreground color, while 40-37 selects the background. Few terminals implements brighter
9color, providing 8 additional foreground and background colors.
10
11### Examples
12
13* to get black letters on white background - **ESC[30;47m**.
14* to get brighter colors with black letters on white background - **ESC[90;107m**. (+60)
15* to reset all attributes - **ESC[0m**.
16
17### 8bit
18
19As [256-color](https://en.wikipedia.org/wiki/8-bit_color) lookup tables became common on graphic cards, escape sequences were added to select from a pre-defined set of 256 colors
20
21### Examples
22
23* ESC[ 38;5;⟨n⟩m Select foreground color
24* ESC[ 48;5;⟨n⟩m Select background color \
25* ESC[ 38;5;⟨n1⟩;48;5;⟨n2⟩m both foreground and background \
260 - 7:  standard colors (as in ESC [ 30–37 m) \
278 - 15:  high intensity colors (as in ESC [ 90–97 m) \
2816 - 231:  6 × 6 × 6 cube (216 colors): 16 + 36 × r + 6 × g + b (0 ≤ r, g, b ≤ 5) \
29232-255:  grayscale from black to white in 24 steps
