What is the Color Category?
WHITE – because of its Value of 9.23 and Chroma of 0.30. Because of its nuance, Ceiling Bright White might show up actually looking bluish gray.
Nuance is an interesting color concept – it means that you consider a color’s Value and Chroma at the same time. CBW has the potential to flash bluish-gray because of where it sits on the Value pole (which is represented with eye icons on the Colorography) and also its Chroma which is 0.30.
It’s the combination of the distance on the Value pole from a true neutral white AND an extremely low Chroma of 0.30.
In other words, CBW doesn’t have an amount of Chroma to off set it from a neutral not true white Value of 9.23.
These characteristics are ideal for many in terms of what they think a bright white ceiling should look like.
While others prefer a warmer option; for them I recommend PPG’s Delicate White.
The best thing to do is get a Samplize Peel & Stick Sample of both so you can compare. Get Samplize Delicate White | Get Samplize Ceiling Bright White.
