Is the tinting in question one of whites appearing slightly pink or something else?
Edit: I've read about the issue and it seems to be one of uneven colour at different areas of the screen. This isn't actually something I found particularly noticeable when I was using the U2410, but it sounds as if some specific units suffer more than others. Given this, I would probably stay clear of that monitor since you are going to be doing a lot of "white space" work.
The tinting on screens relates to the IPS panel construction by LG. It can appear as a left to right, top to bottom, or diagonal tint. It presents itself as a certain colour of tint on one side and either no tint or a different coloured tint on the other side. IE you might have green tint at the bottom left and red at the top right (a diagonal tint) or it may only be red at the top right with no tint at the opposite corner.
The tint can be either Red (which looks pink on pale backgrounds), Green, or Blue. It is always present but is mostly visible on uniform backgrounds, particularly medium-light greys, but also white. The severity of the colour gradation can also range from difficult to notice on all but very specific shades of grey (and even then not that bad) to very obvious all the time. I think most U2410's probably have it to some degree, but in my own case it's so mild that I consider it a non-issue. I had 2 other U2410's were I considered it a major issue though..
I have little doubt that, in the U2410's case, the problem is made worse by the back light which produces its very wide colour gamut (103% NTSC - most monitors are much less) and so any perception of tint, particularly red or green, is likewise boosted. I'm ok with my U2410's uniformity, but I would not recommend that route if you have the money to avoid the potential annoyances I had to go through to get a screen I was happy with. The quality is too random and there's a reasonably high chance you'll get a screen with either noticeable tint or dead pixels (due to the nature of IPS panels it appears you face at least double the risk of a TN panel when it comes to dead pixels).
On the other side Dell will point out (and I believe them.. ) that very few users report these problems. I think that says more about the users, and the fact that they've just paid twice as much for a screen as they had to, because if they're happy with tinted screens (and don't notice it) they'd surely be just as happy with a TN panel..
The problem with screens like the U2410 is they're built to a price point where the grade of panel purchased from LG is highly variable. Keep in mind these screens are £250 in the rest of the World and, much as though people would love to imply it's all because of import taxes, Dell overcharge the UK for these screens which mean raised expectations for the reality of what they can deliver within their "real" (and not rip-off-Britian) price point.
It also means they do not include corrective controls within the panel which can minimize these problems. These corrective electronics are what tend to seperate the high end screens from the consumer ones. Although, as stated above, they are not a perfect solution (but still usually much better than no solution).
If you get a U2410 with excellent uniformity then, in a lot of ways, it'll be just as good as a much more expensive screen for a fraction of the price. However I would personally avoid a wide gamut monitor now unless the panel was a native 10 bit panel. This is due to the limitations colour managed applications have when using ICM files to emulate sRGB colours (8 bit panels drop several million of their 16.7 million colour values to emulate sRGB when using an ICM file). The colours do look like a standard sRGB screen on the U2410, but I can't help thinking they look kinda washed out compared to a native 8 bit panel sRGB screen.
I would look to something like the upcoming HP ZR24w or even a 24" Apple Cinema Display instead. Although not perfect either, where colour uniformity problems do exist on things like the Apple they might be less noticeable because of the narrower standard gamut. It's those or NEC/Eizo etc..
