Defining a colour is a perversely difficult task. Does the RAL system offer anything unique? Wikipedia tells us it is based on the CIELAB and expresses color in terms of it's hue, saturation and lightness. But does it have any advantage over (for example) the Munsell color space? Or is the difference between the two just a cultural thing, like Celsius and Fahrenheit?
Hue is the beast in the box. How many other natural phenomena are expressed as terms, not degrees of intensity?
I often imagine how much simpler color science would be if humans did not possess the ability to perceive hue difference. Indeed color would likely be perceived as too simple a phenomenon to warrent scientific enquiry.
