title: Custom Color Dialog in Windows Forms
body: <p>Is there a way to have the color dialog display on the form without the window border? To make things a bit more clearer, I want it sort of like the one used in the Paint program so that I'm able to change colors of lines drawn on a picturebox without having to open up the dialog again and again: <img src="https://i.stack.imgur.com/vh01I.gif" alt="paint"></p>
  
  <p>I'm placing it inside a vertical groupbox, and I want it to be able to fit in it. Can it be done?</p>
