A very welcome coolness kicks in when Autumn comes round each year to bring relief to our collective, overheated flesh, in those of us living in Dubai. With this season comes a marked reduction in not only temperatures and humidity levels, but also, mercifully, sandstorms (here known as shamal) and as such visibility becomes extraordinary.
Skies come over baby blue eyes one day, then azure the next. Nary a cloud in sight for the next 3 months. By December we will receive rain but for now its all about a luminous sky, saturated hues of blue and bright light bouncing off an urban sea of metal.
Camels are beloved creatures of the United Arab Emirates and rendered in all sorts of material.
Hue, saturation, and brightness are aspects of colour in the red, green, and blue scheme. All possible colors can be specified according to hue, saturation, and brightness (also called brilliance ), just as colors can be represented in terms of the red, green, and blue components.
Most sources of visible light contain energy over a band of wavelengths.
Hue is the wavelength within the visible-light spectrum at which the energy output from a source is greatest. This is shown as the peak of the curves in the graph of intensity (amps) vs wavelength. Here, all three colors have the same hue, with wavelength=500 nm.
Red, Green & Blue: same Hue – as measured by their same wavelength
Saturation is an expression for the relative bandwidth of the visible output from a light source. In the graph, saturation is represented by the steepness of the slopes of the curves. Here, the red curve represents a color having low saturation, the green curve represents a color having greater saturation, and the blue curve represents a color with high saturation.
As saturation increases, colors appear more “pure.” As saturation decreases, colors appear more “washed-out.”

Brightness is a relative expression of the intensity of the energy output of a visible light source. It can be expressed as a total energy value (different for each of the curves in the diagram), or as the amplitude at the wavelength where the intensity is greatest (identical for all three curves). In the red, green, blue color model, the amplitudes of red, green, and blue for a particular color can each range from 0 to 100% of full brilliance.
Saturated skies of Dubai
Dubai, we truly do love you when Autumn sweeps in with her chilled out breezes and cooler temperatures. Forget autumn foliage and autumn harvests; this city is built by hand, forged with metal and encased in glass. Colours bright, light, saturated and blue.
