The scientific analysis of the pigments shows
that this painting is characteristic of the blue period of Picasso. Indeed,
this portrait is almost monochrome where blue prevails, where «
everything turns into blue » which is clouded in a halo of blue
and is in reality a harmony of only two blues which Picasso modulated
according to their use:
- Cobalt blue.
- Prussian blue.
These two blues were not only used by Picasso at that time,
but the use of Prussian blue was rather rare and particular to Picasso.
According to what Picasso told Pierre Daix, he started
to paint in blue after the suicide of his friend Casamegas in 1901. The
colour blue allowed him to express at the same time the misery and the
despair of the world (particularly in 1903). This can be found again in
Woman in Blue with a Beret who is afflicted with strabismus.
In April/May 1903, Picasso comes out of his melancholia and starts to
lighten the melancholic blue of his paintings by using light rose modulations
and also more or less dark rosy ochres, the latter particularly on the
face. It is important to remember that Woman in blue with a Beret
is dated 4/8/03 on the front.
