title: Change colour of substring
body: <p>Is this possible? For example, if I had a label:</p>
  
  <pre><code>lblsentence.Text = "Blue is my favourite colour, and Red is my least favourite"
  </code></pre>
  
  <p>Could I change <code>"Blue"</code> and <code>"Red"</code> to different colours, and leave the rest of the label text default (Black)?</p>
