Although in its infancy, the idea of a colourful economy is bright enough: every purchase has more sides to it than just its price. This is currently also shown with labels such as "Fair Trade" (chocolate for which no children had to be enslaved) and "Eco" (grown with respect for nature and animals).

Barry Voeten's colourful economy defines prices in 3 colours:

• Blue for things that cannot be recycled;
• Green for things that are being recycled;
• Red for things like love and energy.

This pricing scheme is implemented in a trading site that is open to all. An example price is 3 Red + 5 Green. By not flattening everything to a single currency, it remains visible what consequences stick to one's purchases. By having a balance in these three colours, it is possible to quickly oversee how your spending behaviour compares to that of others.

As explained this is all rather raw, but the concept is worth an investigation. Try it and see if you can appreciate this alternative model of pricing. Perhaps add some offers of your own, or look into GroenGemak offers. And if you have feedback, be sure to send it to the makers -- they are very open to learning new ways of looking at their model!
