White is the lightest color you can see. It is also known as an achromatic color, which means it has no chroma or hue. You can see white in things like milk, chalk, or fresh snow.

When light hits a white object, it reflects and scatters almost all the visible wavelengths. This is why white objects look so bright to our eyes. On a computer or a television screen, white is actually a mixture of red, blue, and green light. To paint with white, people use special substances called pigments. One of the most common pigments used today is titanium dioxide.

How white works depends on how light moves. When light hits a surface, it can be soaked up or bounced back. White surfaces are amazing because they bounce almost all the light back at you. This scattering of light is what makes the color appear so bright.

In the past, artists had to work hard to find ways to make things look white. They used materials like calcite or chalk to add highlights to their drawings. Even in the Lascaux Cave in France, artists used these materials 18,000 years ago. They combined them with red and yellow ochre to make vivid cave paintings.

Humans have used white to tell stories for a very long time. In ancient Egypt, white linen was used to wrap mummies. Priests and priestesses of the goddess Isis also dressed only in white.

In ancient Rome, white was a very important symbol for people. All Roman citizens over the age of 14 or 18 wore a plain white toga called a toga virilis. Some leaders wore a special version called a toga praetexta with a purple stripe. Even the word "candidate" comes from the Roman practice of wearing a bright white toga called a toga candida. This word comes from the Latin word candere, which means to shine.

White has many different meanings in different parts of the world. In many Western cultures, brides wear white dresses to show purity. However, in many Asian cultures, white is actually the color used for mourning.

Religion also uses white to show special things. The pope has worn white since 1566 to represent sacrifice and purity. In Japan, pilgrims in the Shinto religion also wear white. Different languages even have many different words for white. The Inuit language has seven words for different shades of white. Sanskrit has specific words for the white of teeth, pearls, or even stars.

Modern science has changed how we use this color. For a long time, painters used a pigment called lead white. This was a very difficult and toxic substance to make. Between 1916 and 1918, companies began making titanium white instead. This new pigment was discovered by the German chemist Martin Klaproth. It is much brighter and has twice the covering power of lead white. By 1945, most of the white pigments sold were made from titanium. Today, architects and artists still use white to show simplicity and modern style.
