Please tell me this isn't what I think it is

So I cruise on over to the web site of Wingnut Maureen Maureen O'Connell, mainly to check whether she's got any mention of a woman's right to choose (nope) or has finally acknowledged being a republican (ditto). These are sore subjects, it seems, for that campaign.
While there, I checked her District Map page, reproduced above. And here's my question: what do the shadings of that map signify?
Please tell me the shades of brown don't stand for 'this is where the brown people live'. That would be just unbelievably crass.
[Update]: Okay, Okay, it's not about the brown people. Still, considering the republican track record, it's not as if that would be a totally unheard-of assumption.
2007 Special Elections | WTF | New York | Barking crazy rightwingers | Maureen O'Connell | Nassau
Here's the deal
Start with: http://www.nyssenate1.com/district_map.asp then increase the district number and work your way up:
http://www.nyssenate2.com/district_map.asp , etc...
You'll notice this is just how the mapping program works, but that there is NO standard view of the district maps AND that nssenate7.com has this lovely page as I pointed out in my diary: NYSSENATE7.COM Disappeared? you get the very un-user friendly "Bad Request (Invalid Hostname)" page. Nothing about the district, nothing about the special election, no district map. . . you are OUT OF LUCK if you go to our NY State Senate page looking for information.
Funny how O'Connell was able to get that map when it no longer exists on the senate pages!

Nice try, but Kings Point does not have more blacks than Elmont
The shaded areas are not where the darker skinned members of the district live. If that were the case, Elmont (the southernmost part of the district) would be very dark, and Sands Point, Kings Point and the rest of the district (with the exception of Westbury and New Cassel) would be completely white.
I doubt it.
Some of those darker shaded areas, particularly along the North Shore, are rather ritzy. I think they are townships. Judging by the juxtaposition of the different colors, I'm guessing it's visibility shading - you know, the same way as on a map of South America they might make Brazil yellow, Argentina pink, Chile blue, Ecuador green etc. to make it easier to see the boundaries.
I know, my first instinct is to expect the worst of her, too, but I have a feeling this is pretty innocent.

Mike, I know your intent is
Mike, I know your intent is good, but you are so dead wrong you should delete this, it's an embarrassment. Couldn't you have run it by someone in the campaign first?
I assume the colors indicate incorporated villages, and the white are unincorporated. Couldn't explain the differential in the colors, though, but I'll bet someone with Johnson can.
Your race theory is just crackpot, and if you ever spent time in this district you'd know it.















Shady business?
Much as I'd like to accuse yet another Republican of being a racist as well, I wonder if the shaded areas represent higher-population areas.
It seems reasonable.
