Dear Marwa Ali,

Let me first thank you for the polite salutation of your post. One
thing to note: I assume the readers of this group will indeed be
mostly male given the group's nerdy subject. However, I know of at
least one female reader of this group. As such the salutation 'Dear
Sir' might be considered improper.

Anyways, if you want to plot data you may consider more specialised
commands to do this. I'd say you could try ListPointPlot3D or its

If you still want to use Graphics3D, coloring can be done by inserting
a color before the drawing commands that should be in that color, for
instance using RGBColor[r,g,b] or some named colors:

ListPlot has the option PlotMarkers to specify the plot symbols.
ListPointPlot3D doesn't have this option, but since markers are
usually 2D they make less sense in 3D plots.

Cheers -- Sjoerd
