The main advantage to red figure painting over black figure painting is a. it requires only one firing before it can be glazed. b. it allowed artists to include greater detail in the anatomy of the painted figures. c. it can be fired at a low temperature because it is non-conductive and non-porous. d. it allowed artists to add pigment to their artistic designs.

The correct answer is b. it allowed artists to include greater detail in the anatomy of the painted figures

Specialists defend that using black paint in the background is easier than using it on figures. Black figures are hard to manage, while you use a red-figure you can gain details over a darker background.  

Explanation:

Using red on a black background is a technique that Ancient Greek created around 530 BC. This technique substituted the black-figure painting on raw pottery and, as a result, the figures have got more anatomy and movement.  

Pottery was part of many civilizations' daily life, and in Greece, they were adorned with scenes of battles or myths. Differently from sculptures, which were made for devotion, the potteries had a utility sense.

The vessels received a hemogenic lay of black painting before being fired. Then the scenes were colored in red with the adding of a few different colors from the same palette.  

The advantage of doing so is that black painting is harder to focus on details, as it annuls other colors. As our eyes tend to search for lightened spots, black-figures tend to look smaller and we focus our attention on other elements.

While red is a very strong color and detaches from any other ones, red-figures are easier to deal with. When they’re disposed on a darker background, our eyes focus on them and every detail is highlighted.

This technique was also incorporated by painters and adopted in painting teaching at the academies of art. We can notice them mostly in Baroque Paintings, as they were highly centered in the figures, but even post-modern movements like abstractionists have used this method largely.
