T61 screen temperature

[geohsia]

Hi,
I've had my T61 for about 3 years now and have been on the road almost constantly. Now that I'm back home I'm noticing that my screen color temperature runs a bit warm compared to my old CRT. I don't think there's an issue with the connection. Is there a way I can adjust the temperature of my display? I know for instance on my desktop CRT the menu has a option for temperature display. I know that for color-critical work I should make my way to the W510 but until then, what can I do with my trusty T61?
