Final answer:
While the specific painting of the little girl in the blue dress is not identified, the use of blue in artwork, as seen in the Girl with Pearl Earring and Matisse's paintings, is significant for evoking depth and focus in visual art.
Step-by-step explanation:
The question of where the painting of the little girl in the blue dress hangs is not directly addressed in the provided reference information. Nonetheless, we can discuss paintings mentioned in the references, such as the Girl with Pearl Earring, often compared to the Mona Lisa and notable for the blue color in the girl's turban and the enigmatic light on her face.
Similarly, Matisse's Woman with a Hat represents artistic use of blue to create depth, and the iconic La Danse, commissioned by a Russian industrialist, utilizes blue against green to evoke the viewers' imagination.
In the context of paintings, the use of the color blue is significant for drawing the viewer's eye and adding depth to the work. Whether in historical depictions of goddesses or notable portraits and murals, the color brings life to the canvas and often symbolizes aspects like the sky or water.
The exact location of a painting would typically be found in the artwork's provenance or current exhibition details, which could involve a museum, gallery, or private collection.
