Cobalt blue hue

 A while ago, someone asked me if I could make one painting for them with a specific color. Since then I used the color much more often. Cobalt blue. I like the color blue, especially comined with black. So i made them a painting ( 150 x 100 if I remember it well ) with Cobalt blue and black! this is the result :

You do not see it on this picture, but the black background is '3D'. you can feel the background. When there's light on it you will see the shadows of the background. I like it.
