I'm trying to use Apple script to set the font color of all selected PowerPoint shapes. I used something similar to this to set fill and line color, but I haven't been able to get it to work for font color.
tell application "Microsoft PowerPoint"
set theShapeRange to shape range of selection of active window
set n to (count shapes of theShapeRange)
repeat with i from 1 to n
tell shape i of theShapeRange
set font color of text range of it to {99, 99, 99}
end tell
end repeat
end tell
Based on the guidance provided by Mockman in a comment above, this seems to work.
tell application "Microsoft PowerPoint"
set theShapeRange to shape range of selection of active window
set n to (count shapes of theShapeRange)
repeat with i from 1 to n
tell shape i of theShapeRange
set font color of font of text range of text frame of it to {99, 99, 99}
end tell
end repeat
