Pantone teams with ad agency for Jubilee-themed colour guide

According to Pantone Colour Institute executive director Leatrice Eiseman, the book has been designed to "capture and commemorate some of the Queen’s most memorable colour choices".

Printed by Precision Printing in Barking, it features Pantone 12-0755 Primrose Yellow, her royal wedding outfit last year; Pantone 13-4411 Crystal Blue, a staple colour in her wardrobe; and Pantone 12-5414 Ice Green, worn during her visit to Ireland, when she was the first monarch to visit since the country gained independence in the 1920s.

Eiseman said: "The Queen’s decision to favour one colour in every outfit is a strong style statement. Monochromatic colour schemes make the wearer appear taller, delivering a more stately air – perfect given that Queen Elizabeth is not tall at 5’4’’.

"Choosing one colour theme also ensures the outfit does not detract attention from the wearer – which is particularly important if you’re the Queen."

Leo Burnett London executive creative director Justin Tindall added: "When you see footage of or read commentary about  Queen Elizabeth on her official engagements, at a Royal Wedding or even watching her horse race at the Derby, there is always mention of what she’s wearing. It has been an ever-present subtext to the 60-year reign of our Monarch."
