Do Hibiscus change color? I planted a red one and the next year it came back pink. Does it have something to do with the soil acidity?

It could be a lack of nutrients in the soil, or that the plant is getting more sun than it did last year. Both of these can influence the vividness of color on the flower. It may also be that the original plant was grafted and the scion (the part you saw last year) died and was replaced by the rootstock which produces a different color.
