Questions and answers

Is there a color by number cake?

Yes, the page opens on it: a slice with red frosting, yellow cake, a brown layer and one blue candle, on a blue plate. Three candles is a second cake picture, a close view of the frosting.

Is there a happy birthday color by number with the words on it?

No. A grid 12 or 24 squares across is too small to spell the words, so these sheets show party things. The printed sheet has a name line at the top.

Which birthday picture is quickest to color?

Three candles: 81 squares on the easy grid, in five crayons. The Balloon dog needs the fewest crayons, 2, but its purple background fills the rest of the grid.
