Each tech layer configuration object should have the following properties:

• id: electrification code;
• label: label for the electrification type;
• color: color hex code or gep color name to be used on map and legend.

The front-end defines default color values for pre-defined technologies. Although these can be changed, it is not recommended as it may confuse the user. Please refer to this file in order to know which colors are available.
