A colour hunt. This is a similar concept to a Rainbow Leaves hunt. It’s simple and you can do it inside or outside. Just look around the house for items or toys of a particular colour, or my favourite: go outside and do a hunt in nature. When you take the time to look, really look at colours, it’s amazing at what variations you can find. Our house here in NZ has a lovely backyard, and take a look at all the different shades of purple, right at my back door!
I use the Palette Picker App to pick out colours in my images like this.
