Over the years, Rainbow Village painter Huang Yung-fu has created a variety of colorful artworks throughout the remaining buildings of the village, including ones of birds, animals, and people. The brick walls on either side are painted with fascinating images in bold and lively colors, mainly pink and light blue, while the road has a magnificent rainbow. The figures on the walls have childlike lines and colors that seem to have splashed fully formed from the paint bucket, brightening up the lives of the visitors as much as the village.
