title: How to select items in JQ based on value in array
body: <p>I have a file with lines like this:</p>
  
  <pre><code>{"items":["blue","green"]}
  {"items":["yellow","green"]}
  {"items":["blue","pink"]}
  </code></pre>
  
  <p>How can I use <a href="http://stedolan.github.io/jq/" rel="noreferrer">jq</a> to select and show only the JSON values that have "blue" in their "items" array?</p>
  
  <p>So the output would be:</p>
  
  <pre><code>{"items":["blue","green"]}
  {"items":["blue","pink"]}
  </code></pre>
