Overriding the colors of RalOption

The Magento extensio RalOption offers a way to display a product-option for a RAL-colorcode within your Magento frontend. A popup displays all colors, allowing the customer to select the right color for that specific product. But the colors might not be sorted in the way you want. Worse, not all RAL-colors can be matched with a webcolor. This tutorial shows you how to override the default behaviour of RalOption as you see fit.
