Created especially for those working in interior design and architecture, Crown Paints' professional pack contains the must-haves for starting interior design projects.

Five readers will each win a pack containing a copy of Interior Colour Book, which acts as a comprehensive colour design guide for commercial projects, a Colourkey unit, and Crown Paints' Colour Collection Fan deck featuring the brand's colours as well as known British Standard and RAL colours.

The second in a series of colour inspiration guides, the Interior Colour Book was created by Crown Paints' team of colour specialists to bring together the expertise required by architects and designers to specify colour effectively across different sectors.

Also included in the professional pack is Crown Paints' new colour measurement and look-up tool Colourkey. Colourkey measures the surface colour using advanced LED technology and finds the closest match using a database of more than 6,000 colours.

It comes with a free-to-download app, is a handy pocket-size and will also give you suggested colour schemes to choose from.

The final item in the pack is a Colour Collection Fandeck, which is a colour reference guide containing over 1400 colours.

"A colour name might offer us an emotional description, but it will always be open to interpretation," said Crown Paints. "That's why it's far more helpful to have a physical sample of your colour, or better still, one that also has its own scientifically measured code."

That's why every colour in the Crown Paints Fandeck is assigned a unique six-digit scan code, which defines the colour by three characteristics: hue, lightness and saturation.

Crown Paints was established in 1777 in Darwen, Lancashire, in the UK. Its head office remains there today.

The company has a manufacturing site in Hull and a network of over 140 Crown Decorating Centres located throughout the UK and Ireland.

The Crown Colour service includes anything from colour consultations to the brand's innovative Pure Paint Samples – fully recyclable samples made using real paint.
