Although my almost 3 yr old daughter had fun painting with these watercolors, they were not vibrant and were quite dull colored. We tried using less water for higher saturation but the colors still looked very water-downed. And if you didn't mix the paint with enough water, nothing would get on the brush. We've tried Crayola and its color saturation and vibrancy is far better than this Melissa & Doug set. So the painting session was fine but the results were disappointing. And we've finished a few colors already just in one painting session.
