title: How to get bot's role color? Discord.js
body: <p>I am trying to match bot's embed color and it's role color. So far I found only this solution, but instead of a user's role color I want bot's color:</p>
  <pre><code>.setColor(message.member.displayHexColor)
  </code></pre>
  <p>I was trying to target the bot with <code>message.author.bot</code> but that doesn't work either.</p>
