For the painting, Self Portrait with Dr. Arrieta by Francisco Jose de Goya, I need to write the two techniques used in it. Help please?

The description and commentary will give you some ideas.

Also look at how light and dark are portrayed. What technique is that called?

And notice how he used color.

Let us know what you think.

oh man this one is a toughy lol, is it watercolor painting maybe?

No, it's an oil painting. Read the section under Details below.

Im not sure it doesnt say the technique in that section
