Y'Raka was a famous artist who had a pessimistic nature to his work.

In 2370, Benjamin Sisko referred to Y'Raka, along with similarily natured Vincent van Gogh and Samuel Beckett as an example of pessimistic artists who created something of great worth. Contrary to this fact, Gideon Seyetik described their works as "dreary, dark and depressing". (DS9: "Second Sight")
