Which painting style became popular in the 1840s due to the availability of tube paints?

The painting style that gained popularity in the 1840s due to the advent of tube paints is Plein Air. This technique involves painting outdoors to capture natural light and atmosphere directly, rather than creating works in a studio setting. The introduction of tube paints made it significantly easier for artists to transport their materials to various locations, enabling them to paint en plein air effectively.

Artists could now easily blend and mix colors while working outside, which allowed for more immediate and spontaneous responses to the natural environment. This shift not only influenced the techniques used by artists but also contributed to a greater emphasis on the effects of light and color, central elements of Plein Air painting. The rise of this technique set the stage for subsequent movements in modern art, particularly Impressionism, which built upon the principles of painting outdoors and capturing the ephemeral qualities of light and atmosphere.

The other styles mentioned, such as Realism and Baroque, do not have the same direct connection to the use of tube paints in the 1840s, as they focus on different subject matters and artistic techniques.
