If you are doing Chantilly Lace on the ceiling do it flat . I used Chantilly Lace on my walls in a flat because I have a new home and they only do flat here for new homes. If your woodwork paint is oil Chantilly Lace will turn in a year to a softer white. Satin is beautiful in oil but not in latex. Latex for moulding should be in semi gloss in my opinion. If you have another room with your gray flooring look at china white with Chantilly lace... I have a lot of gray and china white looks great.

The CIE sets the standards for measuring color. They recommend several ways to measure the wavelengths of light reflected off a color to define a color. There are several standards that are used to measure color, but the LCH values are the easiest way to describe color in a way that is easily visualized. LRV is the Y measurement when using the CIE XYZ standard that measured Pure White will have an CIE LCH value of 100 / 0 / NA under 6504k light L stands for Light - it is directly related to LRV. So the closer to 100 a color is the lighter that color is. C stands for Chroma - the closer to zero the closer to true black, gray or white a color is H stand for Hue. True black, white and gray have no hue as they are the drop dead center of the color spectrum having equal amounts of all color wavelengths. Snowfall is technically lighter than Chantilly Lace, (LRV of 91.6 vs LRV of 91.4 per Benjamin Moore measurements), (Super White has an LRV of 89.5 and Simply White has an LRV of 92.6 per BM) but it also has a higher chroma than Chantilly Lace (4.168 vs 2.538 per easyRGB website) That makes it less white than Chantilly Lace. (Super White has a Chroma of 1.224 and Simply white has a chroma of 4.657 per easyRGB) This is why Benjamin Moore states that their two whitest whites are Chantilly Lace and Super White. Why would Simply White seem like a brighter white It has a higher LRV than any of the other whites and it is more yellow than the other whites. Look at how we see yellow compared to blue or green or gray. So adding just a bit of yellow vs adding a bit of orange or green to the mix may appear cleaner/brighter. Try to remember that we can measure the light waves reflected off of a color to define that color, but the human brain is a highly complex organ (processes 11 million bits of information per second) and we have just begun to scratch the surface of understanding how humans actually perceive color. We don't even know if two people 'see' the same color when we see a red fire engine. We both call the color we see in our brain Red because we have been taught that Red is the name of the color when our eyes receive a specific combination of light waves that we have defined as Red. We do know that women can identify smaller differences in color than men can see. We know that being depressed lowers your ability to see color. We know that we learn color and that Children who are exposed to more color are better at discerning shades of color. Probably the most fascinating thing that I have learned about color is that when pregnant rats were isolated in single color atmospheres that the babies were behaviorally different based on the color the mother was exposed to throughout their lives regardless of what color atmosphere they were placed in. My favorite white is no longer being made, but is color matched well by Benjamin Moore. It is whiter and cleaner than any of the BM whites (Base white with a good dollop of Titanium White added and a small amount of Yellow Oxide added) Devine Icing - CIE-L*Ch(ab) = 96.569 5.785 95.373° Simply White - CIE-L*Ch(ab) = 95.648 4.657 106.615° Chantilly Lace - CIE-L*Ch(ab) = 95.164 2.538 114.465°

You need to see both colors and the countertop sample in your kitchen, with the light that it gets . Don't decide based on what a stranger online tells you, trust your eyes.

@Patricia Colwell - Thank you for being so active on this forum, you’ve provided feedback/input on almost all of my posts. We were leaning towards 5000K for lighting, which appears to be right in the middle, helping create a modern/clean feeling… any cooler, it would become institutional and cold, I assume it would start causing colors to go warmer than intended… you disagree?
