I would not paint the woodwork the same color as the walls. I think it's too important a feature.

White and yellow are a classic combination for a bright, crisp look. However, yellow tends to be overpowering (ask me about my dining room) and for that reason it almost always needs to be either paler than you think you need, or muted. Pale is not the way to go for walls in a north-facing room.

Often the best choice is a yellowish tan rather than a true yellow. One option you should consider is taking the lightest color on the same strip as one of the yellow-tans that were suggested and using that for the woodwork. It will be almost white, but calmer than a true white.

In our previous house I used Benj, Moore barley and other colors on that paint strip in our living room. The walls were one of the paler colors, the fireplace wall was a darker color and the painted mantel was darker yet. The trim was all painted white. (And the adjacent sunroom was the palest color on that strip). Sorry I don't have any pictures. I thought it looked really nice together. I do not remember any more which direction the living room faced, but there were huge oak trees out front shading the windows so it was not a bright room.

These are some great ideas! I am off to the paint store now for samples. Thanks!

I really think we need a pic!

I agree to paint the trim a different color than the walls. If you have all that gorgeous trim why not highlight it! A yellow based tan that I had in my old house that was a pretty color in both direct sunlight and in shadows is SW Ivoire. I'll link to a pic
