We use a [C-like enum] here to explicitly specify the number for each color. Because of the `repr(u8)` attribute each enum variant is stored as an `u8`. Actually 4 bits would be sufficient, but Rust doesn't have an `u4` type.

Normally the compiler would issue a warning for each unused variant. By using the `#[allow(dead_code)]` attribute we disable these warnings for the `Color` enum.
By [deriving] the [`Copy`], [`Clone`], [`Debug`], [`PartialEq`], and [`Eq`] traits, we enable [copy semantics] for the type and make it printable and comparable.

To represent a full color code that specifies foreground and background color, we create a [newtype] on top of `u8`:
