But why is the color blue so rare? The answer stems from the chemistry and physics of how colors are produced — and how we see them. For a flower to appear blue, “it needs to be able to produce a molecule that can absorb very small amounts of energy,” in order to absorb the red part of the spectrum, Kupferschmidt said.
What is the rarest color?
Vantablack is known as the darkest man made pigment. The color, which absorbs almost 100 percent of visible light, was invented by Surrey Nanosystems for space exploration purposes. The special production process and unavailability of vantablack to the general public makes it the rarest color ever.
What colors do not exist?
That’s because, even though those colors exist, you’ve probably never seen them. Red-green and yellow-blue are the so-called “forbidden colors.” Composed of pairs of hues whose light frequencies automatically cancel each other out in the human eye, they’re supposed to be impossible to see simultaneously.

Which is the best blue for food coloring?
Having the right blue color is also important for mixing other colors, such as green. If the blue isn’t right, it will produce muddy, brown colors when mixed, Siegel said. Red cabbage extracts are widely used as a source of natural food colorings, especially reds and purples. These dyes are called anthocyanins.
