Oh no, I wasn't commenting on the design really. I think the design is just fine. I was referring to the joke that a comment above me refers to.

"What's black and white and red all over" A newspaper. It's a play on words where "red" is supposed to be "read". I thought maybe you had that in mind when you chose the colors. It would be really clever and funny if you did. If anyone ever asks you that you should totally tell them yes. I bet they'd get a kick out of that.

He's not saying it's bad -- he's saying that the color scheme is reminiscent of the old joke "What's black and white and red all over" ("A newspaper" as in "re[a]d all over")

The joke also applies to ebooks if you do well, so could be a very appropriate one.
