title: Ruby select with multiple conditions
body: <p>I have an array of hashes:</p>
  
  <pre><code>[{"green" =&gt; 1, "red" =&gt; 2, "blue" =&gt; 3}, {"green" =&gt; 4, "red" =&gt; 5, "blue" =&gt; 6}]
  </code></pre>
  
  <p>I want to select the hash in which either red, blue or green is equal to a certain number.  How would I go about doing this?</p>
