Aegean blue on the island of Crete by Silva Wischeropp

The maritime scene featuring Cretan blue shutters in Amoudara holds a powerful emotional and aesthetic appeal, deeply rooted in our longing to slow down.
The photograph was taken in the early evening, in soft light, using a Nikon D800 (lens: NIKKOR 50.0 mm f/1.4) on 7 August 2026.

The appeal of the characteristic blue shutters found in Crete and on other Greek islands lies in a fascinating blend of practical utility, deep-rooted tradition and political history.
Here are the main reasons behind this iconic architectural style:

1. Practical protection against heat
Cooling effects: The light-coloured combination of white walls and coloured shutters reflects the intense sunlight.

Insect repellent:
Traditionally, a little copper sulphate was mixed into the blue paint. This mixture (known as ‘loulaki’) kept flies and mosquitoes at bay.

2. Historical and political background
National identity: In 1938, the then dictator Ioannis Metaxas ordered that the houses in the Cyclades and other islands be painted blue and white.
Symbol of resistance: The blue and white reflected the colours of the Greek flag. During times of oppression, it served as a silent symbol of patriotism.
Uniform townscape: In the 1970s, this colour combination was made mandatory by law for aesthetic and tourism-related reasons.
3. Cultural symbolism and aesthetics
Protection against the ‘evil eye’: In Greek folklore, the colour blue (cyan) is regarded as a protective charm against envy and misfortune.

Maritime flair:
The blue symbolises the Aegean Sea and the cloudless sky. It provides the perfect contrast to the gleaming white of the limestone walls.
