Kim Hoang paintings, which are often called red paintings, are made on the outskirts of ancient Thang Long. Kim Hoang paintings are printed and drawn on imported coloured paper (yellow, bright red, pink) and printed with black lines and shapes; other colours used to separate the shapes.

The colours are applied in rough, but flexible lines. Sometimes, the paintings are reprinted to create clear line. The colours used for Kim Hoang paintings are bought and then mixed by the painters, except for indigo, which is self-processed. The themes of Kim Hoang paintings are similar to those of the Dong Ho paintings, but there are also Chinese character paintings Phuc, Loc, Tho (meaning “Happiness”, “Good Luck”, and “Longevity” respectively), that have the typical flower of each season printed next to each character.
