Scorpio color: Black
Dark and mysterious black keeps Scorpio intensely inquisitive and focused on transformation. Black represents the depths where the Scorpion resides, and strengthens its drive to look below the surface and question everything. In western culture the color black is associated with death and rebirth, enhancing Scorpio’s strength of letting go and its ability to transform itself.

Bright white and silver connect Cancer with its intuition and provide a clean, clear slate. Like the glistening surface of water or the shining face of the Moon, silver and white are colors of intuition and purity. They increase Cancer’s sensitivity and understanding, allowing love to flow at its deepest level.

Science
"What is color?
When it comes to graphic design, understanding color and how it works in tandem with shade is important. Scientifically, color is an expression of light. Certain materials absorb and reflect specific wavelengths of visible light, which results in objects taking on a certain color to the human eye. A blue flower reflects and disperses blue light back at us while absorbing all other wavelengths of light, so what you see is the color blue. When nearly all light is reflected, you see white. When no light is reflected, you see black."

"Some consider white to be a color, because white light comprises all hues on the visible light spectrum. And many do consider black to be a color, because you combine other pigments to create it on paper. But in a technical sense, black and white are not colors, they’re shades. They augment colors. “And yet they do function like colors. They evoke feelings. They can be a kid’s favorite color,” says graphic designer Jimmy Presler."
