Create a poster for a short film titled "Prohibited colors" (Forbidden Colors). The film criticizes a rigid education system that stifles creativity in children, leading to depression in their early adulthood. Depict a dejected 19-year-old in a dull classroom, with vibrant colors and playful elements locked away or fading in the background. Use bold, restrictive fonts for the title to emphasize suppression.
