Good to know When first applied, the paint doesn't look that bright, but as soon as it dries it becomes more vibrant. We filled the empty muffin tin spaces with plain water so the kids could clean off their brushes before switching to another color.
Fill a muffin tin with a heaping spoonful of corn starch. Pour some water in the corn starch and stir. Add a few drops of food coloring to the mixture and stir in. Take outside and paint on the sidewalk.
