  • What is Colour: Physics of Light

    Key Questions in Design Colour is the range of wavelengths of the electromagnetic spectrum that are visible to the human eye. Physical properties of light Light consists of waves of electromagnetic energy which travel at different wavelengths. Colour is the range of wavelengths of the electromagnetic spectrum that are visible to the human eye. Many…

  • Colour in Islamic Traditions

    Discussion of colour in Islam reveals a lot of disagreement – some colours appear to be recommended or forbidden in clothing (differently for women and men) but there may be different views expressed between Quran itself and Hadith, also between different sects in Islam. Other colours have cultural roots in the different countries in which Islam…

  • Orange (forthcoming)

    Orange is the mixture of yellow and red and absorbs some of the qualities of both. It is brilliant and powerful when pure and, since yellow radiates light and red radiates energy, it is a colour very much associated with radiation. When lighter, tending towards beige, or darker, tending towards brown, it has a neutral…

  • Green (forthcoming)

    Green has the widest range of distinguishable effects. Although of medium brightness, it is the most visible of colours to the human eye. Green is the colour of growth, yellow-green has spring-like associations with youth.  

  • Black

    Source: Wikipedia – Black What is Black: Physics and Optics Black is the darkest color, the result of the absence or complete absorption of light – the visual impression experienced when no visible light reaches the eye. Black is often used to represent darkness; it is the symbolic opposite of white (or brightness). Like white and grey, it is…

  • Red

    What is Red? Physics and optics Red is the colour at the longer-wavelengths end of the spectrum of visible light next to orange, at the opposite end from violet. Red colour has a predominant light wavelength of roughly 620–740 nanometers. Light with a longer wavelength than red but shorter than terahertz radiation and microwave is called…

  • Blue

    Source: Wikipedia Blue and links therefrom What is Blue? Physics and Optics 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. Blues with a higher frequency and thus a shorter wavelength gradually look more violet, while…

  • Yellow

    Sources: Wikipedia  Yellow What is Yellow? Physics and Optics Yellow is the colour between green and orange in the spectrum of visible light. It is the brightest and lightest of all colours. As the colour of sunlight, it is commonly associated with warmth, combined with red with heat and energy. A room painted yellow feels warmer than a…
