Well, you've just written that convenience function yourself :-). It's not
more complicated than that.
The reason there isn't an exported function is because the general case is not
quite as simple as it may seem. For example, BGR and RGB both mean "RGB
colors," but with different internal storage order. Which do you care about,
storage order or "meaning"? When you access a value as `red(col)`, you're
always getting the red channel no matter how it's stored, whereas `comp1(col)`
might give you the red channel or might give you the blue channel. So
"converting to a tuple" might mean different things to different people ("red
first" or "component 1 first"?), which is why there's no general
function---it's
so simple to write, you might as well write it yourself, because you know what
you want it to mean.
When you're dealing with arrays, you can always use `reinterpret` to force an
interpretation.
