I chose the color combo for my dancing Robots of a lime green and baby blue on dark wood. When I delivered the Robots to one of the stores, the owner loved them but then suggested I do them in yellow with glowing red eyes. "Well, that might look cool", I said. And the color door reopened. Hustle-bot might also look good in Aqua, or, what about Aqua with yellow eyes, or red eyes?
When choosing colors I have to consider what is "in" right now in kids' decor. Tiffany Blue is IN, Purple is OUT? What will match the hot new bedding? What is Pottery Barn Kids or Land of Nod highlighting for the season?
I have found a big help in choosing my initial color scheme is matching to fabric. That is how I came up with the Pastel and Vibrant versions of my Safari Baby series. I chose to match the colors to Alexander Henry's 2d Zoo Fabric. By using the colors in the fabric it gives me a basic palette to go by. Of course custom color requests are also always welcome.
And if you are looking to decorate a room in this theme you should check out Etsy because there are many other talented artists using this fabric to create wonderful decor accessories.
