Science Buddies: "Ask an Expert"

In my research proposal, my teacher told me to use a natural pigment to color the paper I will make. May I ask if some of you guys know a plant that could possibly create a color pigment for home made paper?

You can use any color flower petals to make natural pigments. One method is to add each color petals a bunch - 10-15 petals) with 2-3 Table spoon hot water, blend the mixture in a food processor, keep the mixture for few hours to cool down, drain the mixture using a cheese cloth
