// Color represents a color. The low numeric values are the same as used
// by ECMA-48, and beyond that XTerm. A 24-bit RGB value may be used by
// adding in the ColorIsRGB flag. For Color names we use the W3C approved
// color names.
//
// We use a 64-bit integer to allow future expansion if we want to add an
// 8-bit alpha, while still leaving us some room for extra options.
//
// Note that on various terminals colors may be approximated however, or
// not supported at all. If no suitable representation for a color is known,
// the library will simply not set any color, deferring to whatever default
// attributes the terminal uses.
