I love different ways of describing eyes, and colours, and this one allows some range in its definition.  Blue or grey or green, or somewhere on that spectrum? 

‘Eyes the colour of the North Sea in February…’

For further eye colour quotes, meet other sea-related eyes, including a beauty in Orlando.  See too a gem-eyed woman by Miklos Banffy, Gavin Maxwell on goats’ eyes, and Virginia Woolf or Mervyn Peake on perhaps the rarest of eye colours.
