For the design, I want to avoid using dark and gloomy colors such as black or dark gray as they can convey a negative mood, which is contrary to the positive and energetic message we wish to communicate. Please also refrain from incorporating any imagery that suggests workplace accidents or hazards, such as warning signs or images of injuries, as we want to focus on the positive aspects of occupational safety and health. Additionally, avoid overly complex and cluttered backgrounds that might distract from the central message. Simplistic or minimalistic scenery that emphasizes clarity and focus would be preferred.
