I wrote 'I want the pale red coat' but this was marked wrong and the answer given: 'I want the open red coat'. Yet 'pale' is given as one of the definitions of 'ανοιχτό' in the colour list underneath the exercises.
Light in the sense of light color is ανοιχτό (χρώμα). In the sense of light cheese, it's ελαφρύ (τυρί). In the sense of radiance is φως. Languages don't use word-for-word translations.
