You said "background," Doug.
But the principal for vertices is the same. Again, I'm typing this without actually trying it, so caveat emptor:

const Int32 MaximumColorComponentValue = 50;
Random random = new Random();
foreach (IVertex vertex in nodeXLControl.Graph.Vertices)
{
System.Drawing.Color randomDarkColor = System.Drawing.Color.FromArgb(
random.Next(MaximumColorComponentValue),
random.Next(MaximumColorComponentValue),
random.Next(MaximumColorComponentValue)
);
vertex.SetValue(ReservedMetadataKeys.PerColor, randomDarkColor);
}
