In design, a secondary notation is defined as "visual cues which are not part of formal notation". Properties like position, indentation, color, symmetry, when used to convey information, are secondary notation.
A typical example of secondary notation is syntax highlighting of programming code; the colors are not part of the code semantics, but help the programmer to visualize its meaning.
