Holocaust Art: "It Takes But One" by Elizabeth Denholm and Alyssa Dziurlaj

What visual techniques are employed in this painting?

 

The contrast between the black facless people and the arm in the red background with the star of David. This is used to set two things apart or highlight their differences.

The two arms reaching out to each other are vector lines.

The Darkness could represent Nazi Germany and the black leaking down means the Nazi's influence and power seeping over the Jews like a plague of sickness. The two people are reaching out for each other but are unable to touch as the barrier of the contrasting Nazis and Jews between them is holding them back. 

How do these visual techniques highlight major thematic elements of holocaust art and literature?

It highlights the waek Jews and the powerful mighty Germans theme. It represents how the jews were powerless to do any thing and slowly like dripping paint all sucumbed to the darkness.
