I recently got a trial pair of contacts and they're great. However, in dim yellowish lighting, it doesn't 'feel' right. I'm not sure how to explain it. Everything is still sharp as a tack, but at the same time it's weird. I don't have this problem in broad daylight though.

In dim lighting, your pupils expand to allow more light into your eye. It may be that your pupils are larger than "average" and you are therefore seeing into the "sides," so to speak, of your contacts. Thus, your optical zone (the center of your contacts) might be too small for your pupils. Do you also get this feeling at night? Do you get halos/starbursts/other distortions? If so, big pupils are likely the issue. Be sure and tell your eye doctor and they might get you a different set of trials with a larger optical zone to try.

Lifeisgood is correct about one possible cause, but there's another possibility too.
Soft lenses in general reduce contrast sensitivity
In bright light this loss of contrast may not be noticable, but it can cause an odd greyness of vision in poor light.
It can perplex people because the although the letters are still focussed, they don't stand out from the page or screen as they might be expected to.
Some brands of lenses, and some individuals, seem more prone to this.
