Hi Folks,
I am looking for your experience and ideas. In my beloved 100 year old four-square, I have a terrible yellow foyer that I meant to paint out as soon as I bought the house (oops, that was 7 years ago now ;-) But, I have been planning my colours and gathering my art and chair, AND looking at a million grey colours. The plan is to paint the front foyer grey with a crisp white trim, and to stain the stairs a bit darker shade, probably a dark walnut, and I love cool based colours. I am testing CIL Snowfield #00nn 72/000 W/B (the lighter shade in the pic) and CIL Silver Quill 30GG 61/010 W/B (the darker shade in pics).

I am checking the colour appearance at various times of day and exterior weather conditions (the foyer is in the front and the house faces southeast right on the water with almost no trees or any other light restrictions). I am finding that both grey colours that look so cool and light on the slips are taking on a very blue look. I am wondering if maybe all the yellow on surrounding walls is making the colour appear bluer than they really are, and that if I paint out the walls with a great white primer to eliminate the yellow and 2 coats of paint, I will get that cool neutral grey I am looking for. Or, should I be looking a different paint line or a different shade.

I just thought someone else on here may have experienced the same issue. I will paint this 10 times if need be to get the exact colour I want, but I'd like to avoid that time, expense, and frustration.

Thanks in advance for any ideas.
