Color is known to be the acquired appearance as a result of reflection associated with specific visible light frequencies and absorbing others. The science of colors is popularly known as chromatics.

The triggering of the cone cells in the retina results in differentiating spectral sensitivity and color perceptions.

Colour is acquired with the mode of interaction among the eye’s light receptors having different spectral sensitivities and light spectrum. The visual perceptions as blue, yellow, green, red, and others can be categorized under colour.

It depends on physical characteristics like reflection, light absorption, emission spectra, and others.

What is Color?

While using the word as a noun, color is known to be the resultant characteristic appearance that is acquired with the help of reflection of particular frequencies of visible light besides absorbing others.

During reflection, when the frequencies of light are blue on a blue surface, the object shows the characteristic appearance of blue. While using the word as a verb, color is known for providing anything a hue or a shade.

It can be obtained with the help of pencils, paints, or by using digital software. However, writers face several doubts regarding the different spellings of color while writing for the international audience.

Writers often abide by the usage of only one spelling in every place of the writing. Thus, it can be inferred that “color” is largely used when the writing is meant for the audience having American people.

The difference in spectral sensitivity results in a variety of color perceptions based on a variety of cone cells. The degree by which the cells get triggered, different perceptions of colors are obtained.

Color science or better known as Chromatics is claimed to be the science of color. The visible spectrum of colors is as follows- violet, cyan, blue, green, yellow, orange, and red.

What is Colour?

Colour is defined as the property of visual perception that can be corresponded in human beings as red, green, yellow, blue, and others.

It results from the interaction of the spectrum of light with the eye having light receptors constituting spectral sensitivities.

The physical characteristics of colour and categories of colour depend on the physical properties of objects like emission spectra, light absorption, reflection, and others.

The colour of objects is usually determined by the colour of the light surpassing their surfaces traveling at a speed of c through the vacuum without passing through a medium like a prism.

The colour perceived is based on the wave velocity, incident illumination spectrum, the surface’s reflectance features, and the angles of viewing and illumination.

In British English, the word color is spelled as colour. It has the same meaning as the word color.

The word “colour” is valid in every other place where the word, “color” is used. Colour is used by many countries of the commonwealth and is not used in the United States.
