Six small black wallets in plastic protective covers. Each represents the different ranges of colour and tones seen in the colour of people's eyes. A Bernat Klein colour drawing exploring the different shades found in the iris provides the key in making the right colour choices when choosing clothes and accessories. Small woollen samples known as 'thumbnails' represent the colours of the iris. Basic Colours were teamed with Harmonising, Contrasting and Neutral ranges. The 'thumbnails' are designed to be taken out of the wallet and used when purchasing. Also included is an extract of Klein's book Eye for Colour which sets out in detail his 'colour philosophy'.
