I had so much fun doing all the shots of the happy rainbow rose so there is also a photomanipulation with it. The rose was dyed with different colors, it's not digitally manipulated.
How do Happy Roses get their special colors?
White flowers are put in water with natural substances. The stem absorbes this water in a natural way. This changes the color of the flower. Unique selling point is that the inventor succeeded to let every petal get it's own color! He even succeeded to make a rainbow of colors in just one flower! Taken from Happy Colors
