Hi Cad Sunny You have to pass the color to Form2 from Form 1 (or the object you need) as per the following code. And the blog may help you in a better way http://www.c-sharpcorner.com/UploadFile/6f0898/simple-way-to-establish-interaction-between-two-from-inside/ public Form2(Color color) { InitializeComponent(); colorFromFrom1 = color; } Color colorFromFrom1; private void button1_Click(object sender EventArgs e) { System.Drawing.Graphics graphicsObj; graphicsObj = this.panel2.CreateGraphics(); Pen graphPen = new Pen(colorFromFrom1 15); graphicsObj.DrawLine(graphPen 5 10 120 10); } private void button2_Click(object sender EventArgs e) { System.Drawing.Graphics graphicsObj; graphicsObj = this.panel2.CreateGraphics(); Pen graphPen = new Pen(this.panel1.BackColor 15); graphicsObj.DrawLine(graphPen 5 10 120 10); } Regards Selva Ganapathy K
