My Mom and I put 2 white carnations into 4 tall glasses of water with dye. One red, Blue, Green, and Yellow. All sat on the counter together in front of the window. We cut the stems on all the flowers and added equal amounts of dye to each glass. The Yellow changed colour the fastest - 1 day, the blue was next - 2 day, the red next- day 4 and the green was very slow - 6 days. I even re cut the green and added more drops on day 4 and still it took almost 2 more days to show colour. Why do different colours take longer to show? ps, I had a celery stalk with leaves in each glass also and they absorbed colour at the same time line as the flowers. we used food colouring.
