Extended colors can be used for {value} when the terminal supports ANSI color
sequences. These are specified as either 'x' (256-color) or 'x,x,x' (24-bit
truecolor) where x is a number between 0 and 255 inclusive.
truecolor) where x is a number between 0 and 255 inclusive. x may be given as
a normal decimal number or a hexadecimal number, which is prefixed by `0x`.
For example, the following command will change the match background color to
that represented by the rgb value (0,128,255):
rg --colors 'match:bg:0,128,255'
or, equivalently,
rg --colors 'match:bg:0x0,0x80,0xFF'
Note that the the intense and nointense style flags will have no effect when
used alongside these extended color codes.
