The form of art used is Painting. Not being the portrait paintings, these two pieces represent Creative Painting form of art, wherein O’Keeffe’s has used her imagination. The Sky Above The Clouds puts on canvass her imagination to bring out how the sky looks from a height above 30,000 feet from the aeroplane. The painting uses very few colours giving it a sombre look and is one of the most appreciated art pieces of O’Keeffe. The Gray Line puts on canvass a feeling of serenity. It is an abstract painting leaving it for the viewers to understand what it tries to speak. Most of the reviews written on it link it with the beauty of women and the tenderness of women. Both are essentially two-dimensional artworks. It is to be noted here that graphic designs, drawings, paintings belong to the two-dimensional art forms whereas the three-dimensional art form has length, breadth, and height which include sculptures, statues etc. Both the artworks of O’Keffee under discussion belong to the Abstract form of art. This is so because the art itself on its look does not depict anything in the natural world in particular. Instead, it is making use of colours in a non-representational way. It depicts real forms, keeping just an allusion of the original subject that it wants the viewer’s mind to hit. These paintings carry an intrinsic quality of od abstraction making them “non-figurative” “non-objective" as well as "non-representational”. Both the art pieces belong to Fine Arts indicating a form of visual art and are concerned with beauty that appeals to the viewer’s mind.
