title: Customise colour scheme Sublime Text 3.0 build 3143
body: <p>I used to be able to use Package Resource Viewer to customise colours of ST's themes (my favourite: Eiffel), but after the new update, I can edit the colour code but nothing changes.</p>
  
  <p>Do you know how?</p>
  
  <p>Here's what I did:
  Use PackageResourceViewer to open Eiffel.thmTheme file and edit the colour codes in there.</p>
  
  <pre><code>&lt;dict&gt;
              &lt;key&gt;name&lt;/key&gt;
              &lt;string&gt;Comment&lt;/string&gt;
              &lt;key&gt;scope&lt;/key&gt;
              &lt;string&gt;comment&lt;/string&gt;
              &lt;key&gt;settings&lt;/key&gt;
              &lt;dict&gt;
                  &lt;key&gt;fontStyle&lt;/key&gt;
                  &lt;string&gt;italic&lt;/string&gt;
                  &lt;key&gt;foreground&lt;/key&gt;
                  &lt;string&gt;red&lt;/string&gt; &lt;!-- comment colour --&gt;
                  &lt;key&gt;background&lt;/key&gt;
                  &lt;string&gt;yellow&lt;/string&gt; &lt;!-- comment background colour --&gt;
              &lt;/dict&gt;
          &lt;/dict&gt;
  </code></pre>
  
  <p><strong>Update:</strong>
  This is not the same as <a href="https://stackoverflow.com/questions/45437309/is-color-scheme-file-cached">this</a> question, because I'm asking about a method to edit colours in the current version of Sublime. The other question is about how to change colours of header and intersection.</p>
