The number of colors in a rainbow is a frequent source of debate and confusion. Many cite the common mnemonic "Roy G. Biv" and claim rainbows contain 7 colors - red, orange, yellow, green, blue, indigo, and violet.
However, others argue the true number is 6, excluding indigo as a distinct color. So which is correct - does the rainbow have 6 or 7 colors? And so, because the rainbow is an important symbol, it follows that each of the colors represented in the rainbow also holds important meaning and significance. Because of the rainbow's importance across multiple religions and cultural beliefs, the rainbow is packed with symbolism.
Let's take a look at each of the colors and what they mean. What Are the Colors of the Rainbow? As lots of light is refracted through lots of raindrops, we see these colors as a rainbow in the sky. The order the colors come in is set by how long their wavelength is.
When we learn about the rainbow, we are taught that there are seven colors: red, orange, yellow, green, blue, indigo and violet. But this isn't strictly true. There are seven colors in a rainbow: violet, indigo, blue, green, yellow, orange, and red.
However, there are many more colors which are not visible in a rainbow. The colours you see when a rainbow appears are the result of light being split into its various individual wavelengths. As we know, the colors of the rainbow are red, orange, yellow, green, blue, indigo, and violet.
These colors are a result of white light being broken down and dispersed into its different wavelengths by water droplets in the air. How many colors does the rainbow have? It seems like everyone has known for a long time that it has seven colors. But as it turns out, it's not all that simple.
Isaac Newton was the first to identify seven colors in the rainbow: red, orange, yellow, green, blue, dark blue and purple. Newton acknowledged the Pythagoreans theory: Why Does The Rainbow Have 7 Colours? The spectrum was originally subdivided into five colors by him (red, blue, yellow, green, and purple). He then revised the number to seven from five by adding indigo and orange as Pythagoras believed there was a strong connection between music and color.

But elementary school finger painting teaches us that there are three primary colors-red, yellow and blue-that combine to make three secondary colors-orange, green and purple-and (plus or minus some black and white paint) every other color imaginable. That's six basic colors.
But many mysteries and myths still surround the rainbow. One common myth is that all rainbows have 7 distinct colors. In this article, we will explore the science and optics behind rainbow formation to understand if this myth holds true.
