beautify the community
Could bring hope to people with their murals on walls. there is a town in MO that every side of the building is painted. Every time I drive through this down it brightens my day to see the towns history, and the color painted on the buildings sides.
Did this help??
Sometimes artist also express their feelings about the world and current problems. They do through art what writers do with words.
Artists also reflect what's going on in a community or culture or country.
For example, Picasso painted about the horrors of war -- http://www.google.com/search?q=picasso+guernica&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a -- be sure to read that last sentence of the second paragraph in the Wikipedia article.
Another example is Mary Cassatt, who painted mostly about mother-and-child relationships in the culture in which she lived and painted (early 1900s).
You should read about many artists and their backgrounds to understand the wide variety of subjects, as well as the reasons why they painted what they did.
thank you for all your help
