Yeah. I was a little quick about this. This only prints the number of
key-value pairs in the associative array. What we're actually looking
for is this:
% print ${#${(kv)color}}
In any case, `4' is too low a value. what does this print?
% printf '%s = '\''%s'\''\n' ${(kv)color} | sort

Thanks, I'll take a look at it when I'm on the train.

Those flags are used to access the keys and values of an associative
array:
% foo=( bar baz beer booze zack zonk )
% print ${foo[zack]}
zonk
% print ${(k)foo}
zack bar beer
% print ${(v)foo}
zonk baz booze
% print ${(kv)foo}
zack zonk bar baz beer booze
The latter is used to initialise $colour (British) with the same values
as in $color (American).
