Although not the first marque to come up with this concept, you could trust Saab to have designed and made the most beautiful colour samples for their cars. Back in 2002, international Saab showrooms introduced an entire collection of these wonderful models, based on the iconic Saab 92, they're widely known as 'Colour Frogs'.

Created by the Saab Design Studio in Trollhättan, formed from a polyester - fibreglass laminate, sprayed in the various available colours and then simply identified with a discreet line of typography.

Although I've known about these for years, I've never consciously set out to find one, until now. I happened across an image of someone's Saab parked next to a collection of the colour frogs, and became a little obsessed. I began my search to find one for sale, and as luck would have it, found one available in Snow Silver Metallic; the same colours as my latest 9-5 Sportwagon project, it was fate, a few days later it arrived.

I've since sourced a few more, making a small collection, but if anyone has a spare colour frog they no longer need or want, I'd love to hear from you, as I’ll continue to try and collect them. ‘Oh, I have one of these you might like…’
