The Flora Corona™ repertory of colors, gems and flowers are coded in 12 colors, which are opposites or complimentaries of one another in light. The six sets of colors are: Red/ Blue- Orange/ Indigo- Yellow/ Violet- Lime/ Purple- Green/ Magenta- Turquoise/ Carmine. The eye is a light meter and in order to balance itself, projects the opposite color, called the after-image, of the one that it sees. To experience a colors after-image, gaze at the Magenta bottle on the bottom for a few minutes and then at a white space on the right. You will see it's opposite color, Green, shining out over the page.

Why does Flora Corona™ categorize flower essences and gem elixirs according to color? Color is metamorphic. It moves through seasons or stages like nature. Natural metamorphic cycles are: plants that transform from seed to sprout to leafing to buds to blooms to fruits to seeds again, time that moves through seasons of the year, and water that moves through phases of rain to ice to snowflakes to snow & ice to flowing water in rivers, streams and the ocean again.
