If you don't know how to solve this, you can put each word in to the blank and see which sounds right.
Answer:
L'Atelier Rouge which is also known as "The Red Studio" features a contemplative, yet small view of Matisse's recent painting, sculpture, and ceramics, displayed in his studio. The works of art appear in color and in detail, while the room's architecture and furnishings are indicated only by negative gaps in the red surface leading to a theme that can be interpreted as intricate whilst being modest and subtle.
Extra Notes: Seeing artwork displayed at random is to me the most appealing part of said work, the simplicity and carelessness add the feeling that the work is genuine and personal. I feel as if I myself had been there during the passionate, yet delicate original creation of The Red Studio.
Hope this helps! :D
