Just do one stupid thing: replace [color] and {color} in format with ANSI escape codes. That's it.
These color format will be recognized:

clear     :reset the color.
underline :underline
highlight :highlight
red
blue
green
yellow
cyan
black
white
purple
base      :You need to define it.
R;G;B     :RGB color.

Use {color} for foreground color and [color] for background color. Note that cprintf() will always clear the color in the end once you call it, but for background color, you need a [clear] before \n.

Example:

#include "include/cprintf.h"
int main()
{
	cprintf("[green]  [blue]  [green]    [red]  [green]    [clear]\n");
	cprintf("[red]  [green]  [red]  [blue]  [green]  [blue]  [red]  [clear]\n");
	cprintf("[green]  [blue]  [green]    [red]  [green]    [clear]\n");
	cprintf("[green]  [red]  [green]    [blue]  [green]    [clear]\n");
	cprintf("[blue]  [green]  [blue]  [red]  [green]  [red]  [blue]  [clear]\n");
}
