Hi Luv L, This code will help you in better way var frontColor = panel1.BackColor; var backColor = panel2.BackColor; var fValue = frontColor.B > frontColor.G ? "B" : "G"; fValue = frontColor.B > frontColor.R ? fValue : "R"; var bValue = backColor.B > backColor.G ? "B" : "G"; bValue = backColor.B > backColor.R ? bValue : "R"; Bitmap bitmap = new Bitmap(this.pictureBox1.Width, this.pictureBox1.Height); int k = 0; for (int i = 0; i { for (int j = 0; j { k++; if (k > 255) k = 0; Color color; if (fValue == "B") { color = Color.FromArgb(0, 0, k); } else if (fValue == "R") { color = Color.FromArgb(k, 0, 0); } else { color = Color.FromArgb(0, k, 0); } bitmap.SetPixel(j, i, color); k++; if (k > 255) k = 0; j++; if (bValue == "B") { color = Color.FromArgb(0, 0, k); } else if (bValue == "R") { color = Color.FromArgb(k, 0, 0); } else { color = Color.FromArgb(0, k, 0); } bitmap.SetPixel(j, i, color); } } this.pictureBox1.Image = bitmap; Regards, Selva Ganapathy K
