Colours invoke emotions and are crucial to determine how your brand is viewed. Colour has often been associated with a person's emotions in art therapy. It may also influence a person's state of mind. Since the language of colour communicates faster than shapes and words, it works directly on our emotions and feelings. When one thinks of red and yellow, McDonalds is one of the brands that come to mind. Red triggers hunger, appetite and grabs attention, while yellow triggers happiness and playfulness, going well with the brand's image. This colour combination has influenced many other fast food chains too.

Colour is an incredible force, and Coca-Cola has used it to its advantage. Colour is not just a purely visual element; it is psychological and can trigger various feelings and emotions in the human body and mind.

The trademark Coca-Cola appeared in red in advertising as early as 1890s and consumers across the globe identify the very sight of red and white with Coca-Cola. Studies have shown that red triggers impulse buys while white evokes passion.

Peridot is the gem form of the mineral olivine and it is formed in extreme conditions. It is found in rocks created by volcanoes and sometimes due to meteors that land on the earth's surface. The most unique feature of the gem is its fresh lime green colour. Ancient Egyptians considered it a very spiritual stone. Ancient Romans referred to it as the 'evening emerald' owing to its green hue that made it look like deep green emeralds. It is believed to have healing properties and wade off evil spirits too. In Hawaii, the gemstone symbolizes the teardrops of the goddess, Pele.

Zircon is a gemstone that derives its name from Persian 'zargun' meaning golden-colored. The English word 'zircon' is derived from 'Zirkon', which is German for the word. It is often called Hyacinth or Jacinth. According to legend, a mythical hero named Hyacinthus was killed by Apollo because he envied his beauty, which was sealed in red zircon. The gem is believed to bring prosperity, and drive away plagues and evil spirits. It is also believed to prevent nightmares, provide wisdom, honour and riches to the wearer. The loss of lustre of the gem is considered a sign of danger.

The two sexes see colours differently. So, the next time you hear a woman argue about a dress being lilac and not lavender, blame it on physiology. Neuroscientists have found that women excel at distinguishing among subtle distinctions in colour, unlike men. Research has proved that male and female brains process colours in slightly different ways. These intriguing findings come from experiments in which men and women were shown flashes of light and asked to name the colours they saw. All of them had normal vision. Researchers say that these differences in vision may be related to specific sets of thalamic neurons in the brain's primary visual cortex.

Tinamous are birds shaped like tiny ostriches that lay some of the most eye-catching eggs at the base of a tree or in a depression on the ground. Their shells have a mirror-like sheen and hard porcelain-like finish that is produced by a thin and extremely smooth cuticle comprising of calcium carbonate, calcium phosphate, and possibly a mix of organic compounds like proteins. Colours vary according to the species, ranging from chocolate brown, green, blue, purple, violet, steel grey, lemon-yellow to red. In addition to this, one of the Tinamou species lay eggs that change colour depending on what angle you view them from!
