White is the visible expression of all color combined as light. Black is a complete absence of light and therefore color. However, when mixing pigment to obtain a color, mixing all of the primary colors will result in a very dark (black like) color. This is because when you are using tools like markers or paints and you mix it all together, your blob of paint has now absorbed every color and no longer reflects color.
The colour is PURPLE!

The color of visible light is determined by its wavelength. Shorter wavelengths appear blue or violet, while longer wavelengths appear red or orange.
Mixing the colors violet, indigo, blue, green, yellow, orange, and red together in equal parts would result in a muddy brown or black color. Mixing all colors of the visible spectrum will generally result in a dark or neutral color due to the complex interactions of different wavelengths of light.

Red has the longest wavelength, up to 750nm.
The shorter the wavelength of visible light, the higher the frequency and the greater the energy of the photons.
If the lights from all visible wavelengths are combined, they appear to be a white color.
A photon's color is determined by its wavelength, which corresponds to a specific color in the visible spectrum. A photon of shorter wavelength appears bluer while a longer wavelength appears redder. The perception of color in photons is a result of how our eyes detect and interpret different wavelengths of light.
The visible color of an object is the result of light being reflected off its surface. Different colors are perceived based on which wavelengths of light are absorbed and which are reflected. The color we see is determined by the combination of wavelengths that are reflected.
All visible color light waves together make up white light. White light is a combination of all the colors in the visible spectrum, which can be seen when light is dispersed through a prism.
