This popular team’s warthogs return, fresh from their sloppy kitchen counting experience (Warthogs in the Kitchen, 1998), to make a fun mess with buckets of paint. It is raining and the warthogs have decided to paint the wall. First the primaries are introduced: “All colors can be made, I’ve heard it said, / As long as we have some yellow, blue, and red.” (The color words sport the actual color.) They paint great swipes of color on the wall and then get down to their specialty, making a real fiasco, but with enough control to the mayhem to produce orange, green, and purple. “What a terrible mess! But see, it’s clear: / Mixing blue and yellow makes green appear”—in great pools on the floor, which are transferred to the wall. All said and done, a rainbow materializes on the wall. A little color quiz concludes the story. It’s not Margaret Wise Brown’s Color Kittens—there is little of the magic of color here, it’s all process, and the verse is far from transporting—but it is a solid, slapstick introduction to color, plus utterly inspirational when it comes to making a rainy day bright.
