History Of The Colors
The roots of color technology trace back to Ancient Egypt, where visionary chemists concocted recipes for synthetic pigments. Color (Ancient Egyptian name 'iwen') was an essential part of life in ancient Egypt, adding deeper meaning to everything the people created. Paintings, clothing, books, jewelry, and architecture were all imbued with colorful symbolism. ( www.colourlovers.com )
Blue is the favorite color of all people. It’s nature’s color for water and sky, but is rarely found in fruits and vegetables. Blue is the colour between violet and green on the optical spectrum of visible light. Human eyes perceive blue when observing light with a wavelength between 450 and 495 nanometres. ( Wikipedia )
Green is no longer just a color. It's now the symbol of ecology and a verb. Green is the color between blue and yellow on the spectrum of visible light. It is evoked by light with a predominant wavelength of roughly 495–570 nm. ( Wikipedia )
Red is the color of extremes. It’s the color of passionate love, seduction, violence, danger, anger, and adventure. Red is the color at the end of the spectrum of visible light next to orange and opposite violet.[3] It is evoked by light with a predominant wavelength of roughly 620–740 nm. ( Wikipedia )
Orange is vibrant. It’s hot, healthy, fruity and engaging – but it can be abrasive and crass. It’s a polarizing color. People either love it or detest it. Orange is the colour seen by the eye when looking at light with a wavelength between approximately 585–620 nm. ( Wikipedia )
Yellow is the most luminous of all the colors of the spectrum. It’s the color that captures our attention more than any other color. Light with a wavelength of 570–590 nm is yellow, as is light with a suitable mixture of red and green. ( Wikipedia )
Purple’s rarity in nature and the expense of creating the color and has given purple a supernatural aura for centuries. Purple is also the most powerful wavelength of the rainbow – and it’s a color with a powerful history that has evolved over time. Violet is a spectral color – it occupies its own place at the end of the spectrum of light first identified by Newton in 1672, and it has its own wavelength (approximately 380–420 nm) – whereas purple is a combination of two spectral colors, red and blue.

Pink is a combination of the color red and white, a hue that can be described as a tint. It can range from berry (blue-based) pinks to salmon (orange-based) pinks. Its symbolism is complex and its popularity is subject to so many influences. ( Wikipedia )
Is Black a Color? The answer to the question - "Are black and white colors?" - is one of the most debated issues about color. Ask a scientist and you'll get a reply based on physics: “Black is not a color, white is a color.” Ask an artist or a child with crayons and you'll get another: “Black is a color, white is not a color.” ( Wikipedia )
