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
