title: I want to use ImageJ to transforma a grayscale TIF to a colored TIF
body: <p>I have a TIF that was taken with only one color channel. It shows stuff that was Green or Red. But in the most image tools it is only shown as grayscale. </p>
  
  <p>I want to transform this back to a colored image. That shows different values of Green or Red instead of grayscale. </p>
  
  <p>ImageJ show this if I run this commands: </p>
  
  <pre><code>run("Channels Tool...");
  run("Red");
  </code></pre>
  
  <p>but if I save the image the new color is not saved. </p>
