How to change System.Windows.Forms.ToolStripButton highlight/background color when checked?

I have a ToolStripButton that is used as a radio button. When it is checked, a blue outline surrounds the button, but there is no background color. It is not clear enough for the user that the button is checked, so I would like to change the background color to make the check state more visible.

How do I go about changing the highlight color when the Checked property is set to true?

Here is a code snippet:

this.hideInactiveVehiclesToolstripButton.CheckOnClick = true;
this.hideInactiveVehiclesToolstripButton.ForeColor = System.Drawing.Color.Blue;
this.hideInactiveVehiclesToolstripButton.AutoSize = false;
this.hideInactiveVehiclesToolstripButton.DisplayStyle = System.Windows.Forms.ToolStripItemDisplayStyle.Image;
this.hideInactiveVehiclesToolstripButton.Image = global::ClientUI.Properties.Resources.toggleInactive;
this.hideInactiveVehiclesToolstripButton.ImageTransparentColor = System.Drawing.Color.Black;
this.hideInactiveVehiclesToolstripButton.Name = "hideInactiveVehiclesToolstripButton";
this.hideInactiveVehiclesToolstripButton.Size = new System.Drawing.Size(48, 48);
this.hideInactiveVehiclesToolstripButton.Text = "Hide Inactive Vehicles";
this.hideInactiveVehiclesToolstripButton.Click +=new System.EventHandler(this.hideInactiveVehiclesToolstripButton_Click);

Try this, it worked for my app, and I had a similar experience trying the suggested workarounds...

yourStatusStripNameHere.Renderer = new CustomToolStripRenderer();

public class CustomToolStripRenderer : ToolStripProfessionalRenderer
{
    /// <summary>
    /// This will only be called when the ToolStrip is drawn, e.g. TextUpdated, OnLoad, OnRestore, DragOut/DragIn.
    /// </summary>
    /// <param name="e"><see cref="ToolStripRenderEventArgs"/></param>
    protected override void OnRenderToolStripBackground(ToolStripRenderEventArgs e)
    {

        if (!e.AffectedBounds.IsEmpty)
        {
            Debug.WriteLine($"[INFO] Painting the toolstrip at {DateTime.Now.ToLongTimeString()}");
            Rectangle bounds = new Rectangle(Point.Empty, e.AffectedBounds.Size);
            e.Graphics.FillRectangle(Brushes.Navy, bounds);
        }
        else
            base.OnRenderToolStripBackground(e);
    }

}

Here is the VB.net code

Public Class Form1

   Private Sub Form1_Load(sender As Object, e As EventArgs) Handles Me.Load
      toolStrip1.Renderer = New MyRenderer()
   End Sub

   Public Class MyRenderer
      Inherits ToolStripProfessionalRenderer

      Protected Overrides Sub OnRenderButtonBackground(ByVal e As ToolStripItemRenderEventArgs)
          Dim btn As ToolStripButton = e.Item
          If (Not IsDBNull(btn) And btn.CheckOnClick And btn.Checked) Then
              Dim bounds As Rectangle = New Rectangle(Point.Empty, e.Item.Size)
              e.Graphics.FillRectangle(Brushes.Black, bounds)
          End If
      End Sub
End Class

on Event click for every toolStripButton

private void toolStripButton4_Click(object sender, EventArgs e)
        {
            toolStrip1.Items[0].BackColor = SystemColors.ActiveCaption;
            toolStrip1.Items[1].BackColor = SystemColors.Control;
            toolStrip1.Items[2].BackColor = SystemColors.Control;
            toolStrip1.Items[3].BackColor = SystemColors.Control;

        }

You can provide your own tool strip renderer to draw the button's background the way you want them. This example code gives the checked button a very visible black background:

public partial class Form1 : Form {
    public Form1() {
        InitializeComponent();
        toolStrip1.Renderer = new MyRenderer();
    }
    private class MyRenderer : ToolStripProfessionalRenderer {
        protected override void OnRenderButtonBackground(ToolStripItemRenderEventArgs e) {
            var btn = e.Item as ToolStripButton;
            if (btn != null && btn.CheckOnClick && btn.Checked) {
                Rectangle bounds = new Rectangle(Point.Empty, e.Item.Size);
                e.Graphics.FillRectangle(Brushes.Black, bounds);
            }
            else base.OnRenderButtonBackground(e);
        }
    }
}
