Hi Ching-Yen,

You can change the background color of the StartButton using one of the two approaches below:

1. Using Visual Style Builder. To adjust the colors in a theme, navigate to RootRadElement >> RadRibbonBarElement >> RadDropDownButtonElement >> ActionButtonElement >> FillPrimitive or simply click the StartButton while in Design View. Once there, you can set the BackColor, BackColor2, BackColor3 and BackColor4 properties for each of the state tabs.
2. Programmatically. You should access the FillPrimitive of the StartButton and set the colors directly:

   private void Form1_Load(object sender, EventArgs e)
   {
       FillPrimitive fill = radRibbonBar1.RibbonBarElement.ApplicationButtonElement.Children[1].Children[1].Children[0] as FillPrimitive;
   
       fill.BackColor = Color.White;
       fill.BackColor2 = Color.Yellow;
       fill.BackColor3 = Color.Blue;
       fill.BackColor3 = Color.Green;
   }

   
   Please note that this code will override the behavior governed by the theme, so you will lose the effects related to the mouse events.

If you have additional questions, do not hesitate to contact me.
