Believe it or not, most developing countries do not have paint. Usually, trees are used to burn stones and soil to make color powders for paint, and fruits and vegetable (i.e. beets, lime, strawberries, etc.) have to be used to make paint. This outdated practice existed hundred thousand of years ago, simply because people didn't have the today's technology to make paint. However, people who live on less than $2 a day should not have to use their food resources to beautify their homes.
