Meanings of the color blue
The color blue is mainly associated with the colors of the sky and the sea, which enhance its quality as one of the elements of the world. The sky appears blue to us during the day as a result of Rayleigh scattering of sunlight. One of the important properties of dispersion is that waves with a short wavelength are scattered more than waves with a long wavelength. So in fact, we see the blue light in the sky and the sea, which has the shortest wavelength compared to the red light and the yellow light, which are scattered in space and absorbed by the water (which is transparent).

Ultramarine blue. Pigment PB29.
Ultramarine pigment is suitable for any painting medium. Contains red, warm blue hue. The origin of the name ultramarine is from the Latin ultramarinus = "beyond the sea", because the pigment was brought to Europe from mines in Afghanistan by Italian traders in the 14th and 15th centuries. During the Renaissance, ultramarine was the finest and most expensive blue. Its price was higher than the price of gold. Renaissance painters often used it for the clothes of the Virgin Mary and a symbol of holiness and humility. In Persia in the 12th century, the process of producing the pigment was designed by grinding and processing the stone into pieces of lazuli, a long and expensive process, and led to an uneven color. In 1826 synthetic ultramarine was invented. Its production process has been improved to an easy and cheap production of an alternative color, mixed with a semi-transparent acrylic medium. Ultramarine pigment can be made by heating clay, baking soda, sulfur and coal in a kiln.
