Being Too Smart , programmers introduce various kinds of Magic into their software. This will usually lead to a software design that is more generic, dynamic and flexible than is needed, has more features than is needed, and is hence much more complex than is needed. Also, generally, complex solutions will be slower than simple counterparts, will be more prone to containing bugs, will be more difficult to debug, more difficult to maintain, more difficult to explain, and more difficult to learn. Which are, generally, bad things.
The Munsell value has long been used as a perceptually uniform lightness scale. A question of interest is the relationship between the Munsell value scale and the relative luminance . Aware of the Weber–Fechner law , Munsell remarked "Should we use a logarithmic curve or curve of squares?"  Neither option turned out to be quite correct; scientists eventually converged on a roughly cube-root curve, consistent with the Stevens' power law for brightness perception, reflecting the fact that lightness is proportional to the number of nerve impulses per nerve fiber per unit time.  The remainder of this section is a chronology of lightness approximations, leading to CIE LAB .
