How can I change format (specifically the text color) of selected cells based on a text value of another cell.

For example, below are a few cells. If it equal none then I want everything below it grayed out because it doesn't need to be displayed.

NONE
Hole : -
Up : 0 ''
Structure: -

Any Ideas? I know how to gray out the "NONE" using conditional formatting but I can't seem to figure out how to execute the above.
