Sarah Lucas conducted an experiment to test if food dye could alter the color of potted plant petals. She dyed eight plants with four natural and four normal food dyes under controlled conditions. The natural dyes had no effect on petal color and three of the four plants died. The normal dyes colored the petals of all four plants within seven days, also coloring some leaves. In conclusion, normal dyes can change potted plant petal color as hypothesized, but natural dyes had no effect, contradicting the hypothesis. Further questions remained about the different results between dye types.
