Love the concept, Sweet n' Simple; and only clicking required which is great.
can appreciate the all round attention to each category, from the sounds that fit well, to the intuitive particle effects.
also found this is a cool way to practice estimating RGB values, and helping someone having a better sense of the values relating to the colour. If you do more to this project in future would be nice to have an option to show RGB values.
Overall very nice :D
