But the point is that it's always usage dependant.
You key by color names, that seems obvious. But what if you want to look up a color by hex? Now you have to look through them all.
What if this list is actually an order list of colors for different headings? And they can repeat? Then indexing by index is exactly what you want.
Point is, you don't know the reason behind the data structure.
(That said, I do wish the json had a standardized way to remove redundancy for objects that always follow the same structure. One list of property names, and then everything in arrays.)
