Interactive Dinner Art Creation

I'm looking for a creative and engaging experience for a formal dinner event. Guests will be asked to answer four personal preference questions, each associated with a different color. At the end of the night, all their colored answers will be combined to create a unique piece of art.

Requirements:
- Design four personal preference questions
- Assign a color to each answer
- Facilitate the color combination process

Ideal skills and experience:
- Event planning
- Creative thinking
- Art or design background

Looking forward to your creative solutions!
