Using colors like this is an excellent idea, however we shall not rely
on colors alone as several percent of people cannot distinguish colors
due to color blindness [1]. Besides, color blindness may develop with an
advanced age, so no one is color-safe.
We do not hear often about color blindness as people tend not to speak
about it. But in fact maybe up to ten percent cannot see differences
between certain colors at all.

There has been an update to Google Maps styling [1] and I have to say,
they left me impressed.
The overall look is cleaner, which is very welcome after a series of
disappointing changes, but the thing I consider very innovative is how
buildings (and on lower zooms - areas) with lots of "activities" (i.e.
POIs) are highlighted in beige.
Now, traditional topo maps use building type attribute for this, eg.
Polish ones use dark brown for public/retail buildings, orange for
residential, violet for industrial and gray for everything else.
Our (and I presume Google's no better) building type tagging is pretty
sparse, so this is a no-go.
I wonder whether somebody could cook up a proof of concept of this for
OSM styling to see how it would work out. One may play with assigning
different weights to POIs according to their type or perceived
importance via Wiki{pedia|data} tags.
