A unicorn without a preset color scheme is an open invitation. The design here gives you a clear mane, a well-defined body, and a prominent horn — all the essential unicorn elements — without dictating what it should look like when finished.

Pink and purple are the classics, but some kids will go full rainbow, others will pick a single bold color for everything, and a few will use every crayon in the box. All valid. Print extra copies so they can try multiple versions.
