    <p>As its name suggests, its a Unicolor, which is white <a href="http://jcaptcha.sourceforge.net/apidocs/1.0/com/octo/captcha/component/image/backgroundgenerator/UniColorBackgroundGenerator.html" rel="nofollow noreferrer">according to the specs</a>. You can't pass Color as an argument to its constructor. The constructor just take 2 arguments, length and height, respectively. The color will be white and that makes it useless in your case.</p> <p>Now try any of these to achieve your desired thing. The first one is simple, where you can define multiple colors.</p> <ul> <li><a href="http://jcaptcha.sourceforge.net/apidocs/1.0/com/octo/captcha/component/image/backgroundgenerator/FunkyBackgroundGenerator.html" rel="nofollow noreferrer">FunkyBackgroundGenerator</a>, it can be used for gradient too.</li> <li><a href="http://jcaptcha.sourceforge.net/apidocs/1.0/com/octo/captcha/component/image/backgroundgenerator/MultipleShapeBackgroundGenerator.html" rel="nofollow noreferrer">MultipleShapeBackgroundGenerator</a></li> <li><a href="http://jcaptcha.sourceforge.net/apidocs/1.0/com/octo/captcha/component/image/backgroundgenerator/FileReaderRandomBackgroundGenerator.html" rel="nofollow noreferrer">FileReaderRandomBackgroundGenerator</a></li> </ul> <p>Thanks for the Javadocs link. :)</p> <p><strong>[Edited]</strong></p> <p>A spoon feed below, based on your given code.</p> <pre><code>protected void buildInitialFactories() { ColorGenerator cg = new SingleColorGenerator(Color.blue); BackgroundGenerator background = new FunkyBackgroundGenerator(250, 100, cg); } </code></pre>

    3. COnope, the error still exists. Even if I remove the color from the list, or input as white, the `new UniColorBackgroundGenerator` is still producing the `cannot find symbol` error.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
