Vba To Change Color Of Selected Cell

As an example:

Cells C7:F7 are currently shaded light green. Cells G7:L7 are shaded light blue. M7 is shaded dark blue. N7:Q7 are shaded light yellow and R7:T7 are shaded light gray.

When any cell in that range (C7:T7) is clicked (selected), I want the cell color to change to it's normal color; like light yellow to yellow, light blue to blue, dark blue to blue, light green to green and finally light gray to gray.

These cells represent headings for a database. When a heading is selected, the database will sort by that column and the header will change colors. I can do the sort code.

If another header is chosen, the previous selection will need to revert back to it's lighter color and the new selection will change as above... so only ONE cell will be changed from it's "normal state" color at a time. This will serve as an indicator as to which column is being used for the sort. To the user, it will have the appearance of switching on and off.

If any other cell on the sheet is selected, then this should not trigger an event change.
