In this tutorial, I will teach you how to use a ColorDialog in C#. This method has the ability to select a color in a textbox. It shows a form with different colors that you can select to change your text and background color. See the procedure below to see how it works.

Creating Application

Step 1

Open Microsoft Visual Studio 2015 and create a new windows form application for c#. ps1

Step 2

Add a Textbox, button and a colordialog into the form. Do the form just like shown below. ps2

Step 3

Press F7 to open the code editor. In the code editor, create a method for changing the colors of your text and background inside the textbox. 
  1.  
  2.         private void change_forecolor()
  3.         {
  4.             //        'SET THE COLORS THAT YOU HAVE SELECTED TO MATCH 
  5.             //        'THE CURRENTLY COLORS THAT WAS USED IN THE RICHTEXTBOX.  
  6.             colorDialog1.Color = richTextBox1.ForeColor; 
  7.             //        'IT ALLOWS YOU TO CREATE CUSTOM COLORS.
  8.             colorDialog1.AllowFullOpen = true; 
  9.  
  10.             //        'THE BASIC COLORS WILL DISPLAY.
  11.             colorDialog1.AnyColor = true; 
  12.  
  13.             //        'THE DIALOG BOX WILL DISPLAY WITH THE CUSTOM COLOR SETTINGS, SIDE OPEN, AS WELL.
  14.             colorDialog1.FullOpen = false; 
  15.  
  16.             //        'SOLID COLORS ARE ALLOWED.
  17.             colorDialog1.SolidColorOnly = true;
  18.  
  19.             if (colorDialog1.ShowDialog() == DialogResult.OK)
  20.             {
  21.                 richTextBox1.ForeColor = colorDialog1.Color;
  22.             }
  23.  
  24.             //'RESET ALL THE COLORS IN THE DIALOG BOX.
  25.             colorDialog1.Reset();
  26.  
  27.  
  28.         }
  29.  
  30.         private void background_color()
  31.         {
  32.             //        'SET THE COLORS THAT YOU HAVE SELECTED TO MATCH 
  33.             //        'THE CURRENTLY COLORS THAT WAS USED IN THE RICHTEXTBOX.  
  34.             colorDialog1.Color = richTextBox1.BackColor;
  35.  
  36.             //        'IT ALLOWS YOU TO CREATE CUSTOM COLORS.
  37.             colorDialog1.AllowFullOpen = true; 
  38.  
  39.             //        'THE BASIC COLORS WILL DISPLAY.
  40.             colorDialog1.AnyColor = true;  
  41.             //        'THE DIALOG BOX WILL DISPLAY WITH THE CUSTOM COLOR SETTINGS, SIDE OPEN, AS WELL.
  42.             colorDialog1.FullOpen = false; 
  43.             //        'SOLID COLORS ARE ALLOWED.
  44.             colorDialog1.SolidColorOnly = true;
  45.  
  46.             if (colorDialog1.ShowDialog() == DialogResult.OK)
  47.             {
  48.                 richTextBox1.BackColor = colorDialog1.Color;
  49.             }
  50.             //        'RESET ALL THE COLORS IN THE DIALOG BOX.
  51.             colorDialog1.Reset();
  52.  
  53.         }
