Many on-line shop systems, like Magento, Prestashop or xt-commerce, lack the ability to automatically sort products by colour.

In order to solve this, I wrote a little python script that transforms the average colour of a product image into a scalar, then generates a CSV file including the colour value in some property, allowing it to be sorted easily by the web shop system of your choice. Images with many different colours are not sorted very well, but it worked for most of the products in my case.

You can see the script in action at shop.paramentextil.de. It generates a CVS file which can be imported by most e-commerce systems. You will certainly have to change the script to your needs, but this should be easy to do even with little programming experience. Changing the sorting mechanism may also be appropriate in some cases. Enjoy. (weiterlesen …)
