Isn't it fascinating to know that there is a link between colours and emotions? The connections between colours and emotions probably have at least three sources, namely evolution, culture and personal experience. Let us delve into the emotional nuances of the Purple. This colour is associated with creativity, royalty and wealth. Purple is often used to soothe or relax a viewer, which is why it is used in beauty products. If you wish to make a design look richer and luxurious, incorporate purple in your home décor. If you want to evoke a sense of mystery or romance, a lighter purple is your best bet.

Every colour elicits a unique emotional response in the viewer. It is lesser-known to people but has a powerful effect. Spike Jonze's movie 'Her' shows how a movie's entire meaning can be told non-verbally through set decoration and shot composition. The walls, computer screens and clothes are all red. Red is a colour that often invokes feelings of love and passion. The movie's protagonist, Theodore, wears bright red, yellow, blue and white shirts throughout the movie. These colours help communicate his emotional state to the viewers. The entire movie is the perfect example of why colour theory matters and how it can help others perceive someone.

Pyrite
Pyrite is sometimes called Fool's Gold as it is similar to Gold in shape and colour. In the old mining days, Pyrite was sometimes mistaken for Gold, as they frequently occured together. However, both Pyrite and Gold are easily distinguished by simple observation and testing of characteristics. Pyrite occurs in numerous shapes and the smaller crystal aggregates have a beautiful glistening effect under light. The perfect cubes of Pyrite embedded in a matrix from the famous Spanish mines are treasured among collectors.

Kyanite
Kyanite is a gemstone quality aluminium silicate that is sometimes called Disthene, Rhaeticite or Cyanite. The name is derived from the Greek word 'kuanos' or 'kyanos', meaning 'deep blue' as it is blue in colour. However, in addition to blue, Kyanite can also be colourless, green, orange, white, gray or yellow. With this gemstone, colour is not really consistent overall. In fact, most gemstones exhibit areas of light to dark colour zones, along with some blotches or white streaks. Kyanite inspires loyalty and fair treatment to others. In the workplace, Kyanite promotes excellent communication, encourages self-expression and speaking the truth. It instantly aligns all the chakras and restores Qi to the physical body.

Nembrotha cristata
Nembrotha cristata is a colourful type of sea slug that is found in tropical Indo-Western Pacific oceans. Its entire body is covered in black but it has bright green pustules and gills that are neon green. Its bright colouring helps scare away predators, allowing it to safely navigate ocean waters at a slow pace. It belongs to the Polyceridae family and is also known as, Cabbage Nudibranch Sea Slug/Snail or Cabbage Patch Nudibranch. It has two Rhinopores that help it to detect food through taste and scent. It has antenna-like objects on the Nudis head. Fascinating, isn't it?

Keel-Billed Toucan
Like many toucans, keel-billed toucan has one of the most colourful and oversized beaks in the bird world. Though it is more a green colour than anything else, it can be a mixture of green, yellow, red and orange. It has a black plumage, a vibrant yellow throat and cheeks, bright red feathers under its tail and a yellow-green face. Its light green, banana-shaped bill is splashed with orange and tipped with red and blue. It can grow to be a third of the size of the toucan's 20-inch body. It is a very social bird, hardly seen alone. It often duels with the other using its bills, and throwing fruits into each other's mouths. Indeed, a photographer's delight!
