Can we see a purple Colour under blue light?

If by “blue object” you mean “reflects only one wavelength of blue light”, and by “purple light” you actually mean “one wavelength of violet light” then the blue object will not be reflecting any light, so it will look black.

How do we perceive violet light?

We don’t see the greenish hue, however, because of the sky’s violet light. Violet is scattered most by Earth’s atmosphere, but the blue cones in our eyes aren’t as sensitive to it. While our red cones aren’t good at seeing blue or violet light, they are a bit more sensitive to violet than our green cones.

What color isn’t a color?

Technically, pure white is the absence of color. In other words, you can’t mix colors to create white. Therefore, white is the absence of color in the strictest sense of the definition.

Is purple same as violet?

Violet is closely associated with purple. In optics, violet is a spectral color (referring to the color of different single wavelengths of light), whereas purple is the color of various combinations of red and blue (or violet) light, some of which humans perceive as similar to violet.

Why do some people see red and Violet differently than others?

Some people can see further into the ultraviolet and infrared ranges than others, so the “visible light” edges of red and violet are not well-defined. Also, seeing well into one end of the spectrum doesn’t necessarily mean you can see well into the other end of the spectrum.

What is the difference between purple and violet light?

Purple is formed by mixing red and blue in a ratio close to 1:1, whereas violet is perceived by your eyes as containing more blue than red. However, as you can see from the picture above, no spectral colour activates the “blue” path and the “red” path at the ratio of 1:1 without also stimulating the “green” path.

Why is purple not a spectral color?

In other words purple is not a spectral colour. You can have a source of monochromatic violet light (i.e. a source producing just a single wavelength), but everything that looks purple must emit both red and blue light.

Why do purple and Violet look the same to other animals?

The reason why purple and violet look similar to us is because they stimulate our cones in a similar way, but most other animals don’t share the same types of cones and “post-processing”. This means that to other animals, purple and violet may look completely different!
