Discover the Heart of Rainbow Universe
The Heart of Rainbow Universe is an ecosystem in itself.

Its foundation is the 7-volume saga called "Heart of Nature, the Legend of the Rainbow."
The saga tells the adventures of Iris and Ravi in search of the Heart of Nature. The Heart of Nature is a legendary object in the form of a plant-based shell that symbolizes the link between nature and humans. It contains the 7 colors of the rainbow: Grounded Red, Sensuous Orange, Jolly Yellow, Tender Green, Mutual Blue, Intuitive Purple, and Majestic Pink.
Volume 1 discusses Grounded Red, the hidden meaning of this color, and the personality trait it corresponds to. It was released on September 7th 2024 on Books.by.
The rest of the Universe stems from this saga with 2 main axes:
- Live the Heart of Rainbow experience with
1/ individual coaching sessions "Make the Colors of Your Life Shine" and collective workshops focused on one color over one day: 2 formats are possible, short with a one-day collective workshop in a group or long with in-depth individual coaching over 6 months
2/ the 'Well-being in your pocket' website with a Heart of Rainbow quiz to complete to identify your score for each of the 7 colors in the form of a Coeur Nature profile. Thanks to the results, the site will provide personalized activities by Color Focus. This site will be launched later.
