Grids will use any specified foreground or background color. If either color is omitted, then that color uses a system-dependent default value. Under Microsoft Windows, the default values are determined by the settings defined by the user in the Control Panel (usually black on bright-white). Note that the grid's "color" is its default color. You can override this default for a specific row, column, or cell using various special properties (see ROW-COLOR, COLUMN-COLOR, CELL-COLOR, CURSOR-COLOR, HEADING-COLOR and ROW-COLOR-PATTERN below). The grid uses a priority rule for determining which color to use when several are specified for a cell (for example, a cell that has a ROW-COLOR and a different COLUMN-COLOR specified for it). This is discussed in detail in the introduction to the grid above.
