From the pattern:

Peter Rabbit in his little blue sweater can be worked in so many ways, using the charts here for cross-stitch, needlepoint, and even a latch hook rug. Repeated around the bottom of a sweater, Peter can be worked in duplicate stitch, either on a store bought sweater or one your have knitted yourself…

Saddle shoulder sweater is shown in white with Peter Rabbit duplicate stitched in embroidery floss. The chart requires three shades of brown (from chocolate to beige), shades of blue, and a little yellow and pink.
