Many thanks, BobM! The following did it. It looked like SystemColors.Control to me also, but for the life of me, I couldn't get it right.
This is another place where it seems that the spread is sometimes needlessly complicated. Why not expose RowHeader.BackColor, ColumnHeader.BackColor, CornerSheet.BackColor, etc. When you don't live with the product everyday like you guys do, it's hard to remember all of the Styles, etc. I'm not suggesting you do away with all of that because it is really slick, but it seems like there would be room for some simpler ways of doing things as well for common, mundane things that would be reasonably expected to be done on a fairly frequent basis.
.SheetCorner.DefaultStyle.Renderer = New FarPoint.Win.Spread.CellType.CornerRenderer
.SheetCornerStyle.BackColor = SystemColors.Control
