title: SwiftUI: WHere can I get a list of standard colors?
body: <p>In SwiftUI I can assign a color using something like this:</p>
  <pre><code>Text(&quot;…&quot;)
  .background(Color.something)
  </code></pre>
  <p>I know that I can select a number of hard-coded colours, as well as my own custom colours.</p>
  <p>I want to use the standard colours for MacOS appearance theme (I’m not sure what the correct terminology is for that). In particular, I would like to get the standard text background colour (which in the light appearance is white).</p>
  <p>Does SwiftUI have access to these colours, and, if so, where can I find them?</p>
