Do you like to relax in the blue?

Blue is a colour with a wavelength of 450 to 495 nanometres (nm), that sits on the visible spectrum between green and violet, and it has the hex code #0000FF and the RGB value (0, 0, 255).
Blue is among both the three primary colours of light, as in the RGB colour model, and pigments, as seen in the field of art, depicted in the RYB colour wheel.
The words ‘bleu’ and ‘blwe’ are the Old French and English words from where the term ‘blue’ originates, and these come from the Proto-Germanic word ‘blæwaz’.
Common shades of blue include navy, ultramarine, sky, turquoise, cobalt, cyan, indigo, azure and teal.
Natural blue pigments are made from lapis lazuli, azurite, cobalt, or plants such as indigo (Indigofera tinctoria) or woad (Isatis tinctoria), and fabricated versions became available by the 1800s, while in the 1900s, most natural pigments of the colour were replaced with synthetically produced versions.

When viewing items at distance, they will usually look more blue to the human eye, and the colour is commonly used to give depth in art, as it appears to be further away than other colours.
Depending on the shade in question, blue can be used to symbolise trust, intelligence, loyalty, coolness, harmony, infinity and peace.
The sky and bodies of water appear blue, as well as the eyes of approximately 8% of all humans, and some flowers, birds, butterflies, and sea animals, and a small quantity of land creatures also feature the colour, although it is not as common as some hues.
Most likely due to its calm appealing nature, blue has been listed as the world’s most favourite colour.
The colour blue has the ability to bring out or create emotions when used correctly, and this tactic was used by artists in the 1900s.
