title: How can I add 2 tone icons without using any plugin?
body: <p>I don't want to add any plugins just for one icon in my app but I need two tone because the background color will vary and I don't know when it will be dark and when it will be light.</p>
  
  <p>I mean icons like these - <a href="https://material.io/tools/icons/?style=twotone" rel="nofollow noreferrer">https://material.io/tools/icons/?style=twotone</a> where icons have border of different color.</p>
