Purple - a blend of red and blue.
Thought to resemble royalty, luxury, faith, religion and also magic.
I personally associate the colour purple, with the smell of lavender and Amethyst gemstones (my favourite.)
I don't really wear purple clothes too much, but I do like using it in design.
In marketing and branding Purple is considered to represent a creative and imaginative brand and is used a lot in beauty products.
