k Parentheses Colors during Calculation Formula Input

Parentheses are color coded during input and editing of calculation formulas in order to make

it easier to confirm the proper relationship between opening and closing parentheses.

The following rules are applied when assigning parentheses colors.

• When there are nested parentheses, colors are assigned in sequence from the outermost

parentheses inward. Colors are assigned in the following sequence: blue, red, green,

magenta, black. When there are more than five nesting levels, the color sequence is

repeated starting from blue again.
