Answer:
For a preschool, the best choice of colors to create a cheerful and engaging environment would be bright and playful colors. Primary colors like red, blue, and yellow are great options because they are visually stimulating and can promote creativity and imagination. Bold shades of green or orange also work well as they can create a happy, energetic atmosphere. Pastel colors may not be as effective in creating a lively environment, while black and white may appear too stark and less welcoming for young children.
