Sure, just get the color from one of the many ColorTables. I'm pretty sure you can get the ColorTable currently in use from an existing CustomizableToolStrip via
Code:
Dim colors As ColorTable = toolStrip1.Renderer.ColorTable
Perhaps you have to cast the Renderer to ToolStripProfessionalRenderer;
Code:
Dim colors As ColorTable = ((ToolStripProfessionalRenderer)toolStrip1.Renderer).ColorTable
Then just use the color property you need from that
Code:
Dim color As Color = colors.ToolStripGradientMiddle
