For a long time in Kidz Fun Art, the tablet app I built, you could draw with a rainbow brush, which is the favourite feature of many people. I noticed my eldest daughter trying to use it in such a way so to only use a subset of the colors and it was really awkward, so I added this fun new feature where a child can intuitively design their own gradient.
It was a fun challenge to make it both powerful but still intuitive enough for a 3 year old. I think I achieved it, what do you think?
