## cell-unavailable-foreground-color

Arguments: grid-row grid-column

Returns the color in which to draw the foreground of the `grid-widget` cell at the intersection of the specified grid-row and grid-column if the cell is currently unavailable (see cell-available, available, available-reader, and cell-and-sections-available).

The default method returns the value returned by system-disabled-color, which is a color that the end user has specified in the Windows Control Panel. An application may add cell-unavailable-foreground-color methods in order to override the Control Panel defaults for some or all grid cells.

The value must be an RGB color (as returned by make-rgb). Note that the value cannot be an HLS color (as returned by make-hls). If you use HLS colors, apply hls-to-rgb to them before setting this property, and apply rgb-to-hls to get the HLS equivalent of a RGB value.
