The least favorite color for many individuals is yellow. This color is often associated with warm, sunny weather and can evoke happy and joyful memories from childhood. However, in moderation, yellow can also be a bright, cheerful, and invigorating color that energizes the spirit. However, excessive yellow can also be overpowering and stressful to observe, making it a less suitable choice for busy workspaces or living spaces. Ultimately, whether yellow is considered a favorite or least favorite color depends on the personal preferences and individual experiences of each individual.
