The Casta was a system of racial hierarchy used in New Spain and also in the Philippines during and after the Inquisition, based on perceived blood purity. It was determined by birth. Those with darker features had fewer opportunities, as did their children after them.

The Casta system of the Spanish colonies of the Americas neither encouraged nor discouraged the mixing of races, it was simply a hierarchy of races, in which white Europeans had more opportunities and rights than their dark-skinned, indigenous counterparts. This system was the subject of much colonial artwork, as many artists were commissioned to illustrate the different races and the classification of their offspring. The title of the painting, De español y mulata, morisca, translates to English as, "From Spanish and mulatto, comes morisco." This means that the child of pure Spanish blood and mulatto blood (mixed race), would be classified as a morisco.

Hide paintings and oral stories were used by indigenous Native Americans to record their history, as they did not have access to the printing press until after the arrival of European invaders.

The answer is all of the above. The stone tells the story of Coyolxauhqui and her brothers attempting to kill their mother, Coatlicue, when they find out she is pregnant. Instead, Huitzilopochtli (the child she was pregnant with) emerges from Coatlicue's womb fully grown and defeats Coyolxauhqui. The stone depicts the exact moment Coyolxauhqui's body is broken after her beheaded body is thrown down the mountain.

The Lion symbolizes Buddha's royal status. The Wheel denotes Buddha's law. The Lotus is a symbol of Buddha's natural origins. Trees are not a key symbol in the iconographic scheme of Buddhist art.

Monumental landscapes during the Northern Song dynasty are characterized by their use of three distinct perspectives in the composition: high distance, level distance, and deep distance.

Instead of painting in golden hued paint on the screen in his White and Red Plum Blossoms, Ogata Kōrin inlays actual gold leaf onto his work of art, having the gold dominate the work of art. This use of non-paint or ink materials in creating screens was a signature element of the Rinpa school, who also utilized items such as mother of pearl, although gold leaf was by far the most frequent material included in Rinpa school work.

Folding screens are a central part of Japanese art due to their use in Japanese domestic architecture as dividers between different spaces. This meant that screens such as White and Red Plum Blossoms by Ogata Kōrin were central decorative objects in houses during the Edo Period of Japanese history. Ogata Kōrin's work was one of the key developments of folding screens as an art form.

Ukiyo-e was the dominant form of Japanese art in the Edo period (1603-1867), and was aimed largely at the newly dominant upper middle classes by featuring images of geishas, sumo wrestlers, and kabuki actors. Ukiyo-e works were made from woodblock prints that allowed the artist to imprint a similar image on many different pieces of paper after creating just one block. Its handmade nature, however, allowed the pieces to be hand colored and shifted each time a new one was made.

Chinese paintings, whether fashionable court paintings or more individualistic works from the literati, were traditionally presented on hanging silk scrolls. These scrolls were both easily portable and impressive in their scope, as they could be quite large. The manufacture of the scrolls themselves was considered an art form.
