9/// Colors in a 256-value (8-bit) palette
10///
11/// Constants are provided for the initial 16 colors.
12///
13/// `Color256` values can be [parsed][std::str::FromStr] from case-insensitive
14/// names (see [`Color256::name()`]) or from strings of the form
15/// `"color({index})"`.
16///
17/// `Color256` values are [displayed][std::fmt::Display] as their lowercase
18/// names or, for colors without names, as strings of the form
19/// `"color({index})"`.
20///
21/// # Examples
22///
23/// ```
24/// use parse_style::Color256;
25///
26/// assert_eq!("color(2)".parse::<Color256>().unwrap(), Color256(2));
27/// assert_eq!("green".parse::<Color256>().unwrap(), Color256(2));
28/// assert_eq!("GREEN".parse::<Color256>().unwrap(), Color256(2));
29///
30/// assert_eq!(Color256(2).to_string(), "green");
