	      colours (ANSI colours), such as "blue" or "bright red":
	      for example, <TT
CLASS="APPLICATION"
>mutt</TT
> mail reader
	      can use red colour to show urgent messages. However, it
	      is up to the terminal to decide which exact tint to use
	      for "bright red" or "blue". This collection of sixteen
	      colours is called a palette, or "colour scheme".

		white.

>Additionally, the user can drag a colour from the
		rectangular box beneath the colour wheel from any GNOME
		colour selector or colour source and drop it into the
		terminal.  If the user drops the colour on a blank space, it
		will set the background, if the user drops the colour on a
		cell that contains a character, it will change the
		foreground.  This will also automatically change
		foreground/background type to <TT
CLASS="GUILABEL"
><B
>Custom
		colours</B
