I needed a very strong yellow to go in my family room and kitchen area. It was tricky because there were huge spaces of wall but also a lot of  small spaces that created shadows that dramatically changed the color. In addition I needed to match it to the wallpaper in my mudroom which is made by Farrow and Ball. I finally settled on  Frittata(3058) but added 75% white-otherwise it was reading too orange-y. Frittata is made by C2 Paints.
