Sure can - use ARGB instead of RGB and specify a value of 0 to 255 for A(alpha value) to represent the opacity.

EDIT: In your case you are looking for =ARGB(0,0,0,0).

Hi flipside.

Do you have any idea how to convert a ARGB color to RGB color?

Yes, it IS possible, but I have only found out how to base it on a white background. Play about with the colours in the attached and you'll see what I mean.
