The color of a body is composed of the reflection determined by the type of light that this body reflects. White is the combination of reflection of all colors.
Light from the Sun is known as white light and is formed by the sum of seven different colors:
These colors also have velocity, whose decreasing order of velocity goes from red (higher velocity) to violet (lower velocity).
The colors we see are actually the decay that happens with white light. This means that when all these colors are applied, only one will be reflected, for example:
• When a white colored body receives white light it means that it reflects all seven colors that make up that white light.
• A violet body is this color because it receives white light and reflects only the violet, absorbing the others.
• A blackbody absorbs all colors and reflects none of them.
We see then that white is the combination of the reflection of all colors, while black is the absence of this reflection, because it only absorbs light.
Colors are divided into primary and secondary .
Primary colors are those found in nature and unable to decompose.
Example of primary colors: yellow, blue and red.
Secondary colors decompose and can then mix with others.
Example of secondary colors: green, orange and violet.
We can conclude that not all beings can see the color of a body; this is a privilege of the few, and we humans have it.
