Resistor color: no task description

[okeegan]

The explanation for how resistor colors (#1466) work is fine, but in terms of what the task actually is – there's not much there.

These colors are encoded as follows:

Black: 0
Brown: 1
Red: 2
Orange: 3
Yellow: 4
Green: 5
Blue: 6
Violet: 7
Grey: 8
White: 9
Mnemonics map the colors to the numbers, that, when stored as an array, happen to map to their index in the array: Better Be Right Or Your Great Big Values Go Wrong.

More information on the color encoding of resistors can be found in the Electronic color code Wikipedia article

I propose the addition of a line that describes the expected input and output for this exercise. Maybe something like:

"Write a function that takes a band color as input and outputs the associated number."

Hi @okeegan, that's a sensible addition and I'd be happy to accept a pull request, though to make it language/paradigm agnostic and reflect the fact that the canonical data requires more than one function maybe something like "Create the means to list the different band colors and to look up the numerical value associated with a particular band color."?

Color band instead of band color. Otherwise I think that is good.

[okeegan]

In my opinion as a mere noob, "Create the means to list the different band colors..." is implicit in the second half, but otherwise your suggestion rocks @yawpitch.

Also, noted @rpottsoh!
