Alberto Reguera (Spanish) or maybe Mark Rothko?

Reguera work:



Rothko work:



Also, Jacques Monory (French) does all his works in shades of blue:



I'm not quite sure what you're searching for but a good place to start is with Colour Field artists, like Mark Rothko or Barnett Newman. Also look at Malevich and Yves Klein's work for monochromatic art.

I did a quick search and this article on an art exhibition called "Monochromatic Mostly" that might be of interest came up.

Monochromatic Mostly

Whether we write or speak or do but look
We are ever unapparent. What we are
Cannot be transfused into word or book.
Our soul from us is infinitely far.
However much we give our thoughts the will
To be our soul and gesture it abroad,
Our hearts are incommunicable still.
In what we show ourselves we are ignored.
The abyss from soul to soul cannot be bridged
By any skill of thought or trick of seeming.
Unto our very selves we are abridged
When we would utter to our thought our being.
We are our dreams of ourselves, souls by gleams,
And each to each other dreams of others' dreams.

Fernando Pessoa, 1918
