How do you set RGB values for colors in Numbers?

Question

We are trying to set a specific RGB value for the background cell shading in Numbers.   Please help me on how to accomplish this?

Answer 1

And another way is with short scripts.
This one gets the RGB values of the background color of a selected cell:
--get background color of cell -- like a "dropper"
--if none set, returns 'missing value'
tell application "Numbers" to tell front document to tell active sheet to tell (first table whose class of selection range is range)
          tell the first cell of the selection range
                    set bkgrRGB to its background color
          end tell
end tell
And this one sets the background color of selected cells to the RGB values defined in myBackGroundColor:
--sets background color of a cell
property myBackgroundColor : {8607, 65513, 1548}
tell application "Numbers" to tell the front document to tell active sheet to tell (first table whose class of selection range is range)
          repeat with aCell in the selection range
                    tell aCell
                              set its background color to myBackgroundColor
                    end tell
          end repeat
end tell
