Painting - Interior Trim Paint

I need a recommendation for an off white trim paint which is not too yellow or too pink, not too shiny and won't change color much. I want to use an alkyd paint. A decorator recommended Benjamin Moore's Linen White. My paint contractor and some users said that this paint yellows excessively. My paint contractor suggested Glidden's Ultra Traditional but this only comes in a very shiny semi-gloss and I prefer the Satin Impervo degree of sheen. Glidden could not tell me whether their High Hide paint which comes in less of a sheen would hold up as well. I would appreciate hearing any of your experiences good or bad.

Judy,
It hasn't been my experience that Impervo yellows excessively. You're going to get some shift no matter what you use. Keep in mind that depending on the room you view the samples in, the colour is going to shift anyway due to light refraction and colour gain from say, a green lawn or the colour of the house next door, not to mention the artificial lighting.
If it were mine, I'd get a gallon of Impervo and sit down with the tints and mix it 'til we achieved the colour you wanted. Maybe your contractor is willing to do this for you.

my best

Ben. Moore's Impervo is also my chioce of oil based trim paint, it doesn't yellow as much as a lot of the oil based paints I have seen, I have gone back and done touch ups on houses over a year after I painted using Impervo (for good of bussiness, plus I was next door working) and I haven't noticed any yelowing at that time and I would have noticed, being touch-up, but I have seen cheaper oil paints yellow within a couple of months after painting, one brand in perticular yellowed so badly it looked like smoke damage, Enterprise I believe, (a friend used on his house) You can do as Sonnie suggested or go through there vast array of color swatches, take some of the swatches home for comparison.
