I'd ask why he/she thinks it's too dark.

Because in terms of Lightness Value, it's just slightly darker than Pure White and Extra White both have a Value of 9.34.

Another possibility is they mean Chroma, not Value but they don't know how to articulate the right part of color.

Value tells you how light/dark a color looks. Chroma tells you how neutral or colorful a color looks.

Colors of white like Snowbound and Pure White are more colorful, less neutral compared to Extra White, for example.

I really just hate getting into all this explanation. IMO colors work in spaces or not and all the info in the world will not change that. IMO those 2 colors do not work together and I would do much crisper white for the trim. Like Extra White.

Patricia,
I like your simple and direct answer. So if I have SW Origami cabinets AND trim in an open floor plan, what greige , off white or neutral wall color will work without making the Origami look dull.

It is very difficult to demonstrate whites on the internet or to see undertones in whites without large samples. The simple truth is that there is very little 'color' in whites.

Sometimes the most effective way to describe color is by describing the three components that make up a color.

I do use CIE LCH to help people understand the makeup of the color they have chosen and to help get that perfect white to complement their chosen color.

In this case we have White Duck. It is a creamy off white

The LCH values are 88.96 / 7.08 / 91.45

but what does that mean and why don't I agree with the choice of Extra White?

LCH is the Light, Chroma and Hue.

Light how light or dark a color appears.

Chroma is how gray or colorful a color appears

Hue is where a color appears on a color wheel (Red/Orange/Yellow/Green/Blue/Purple)

Every color has these three elements that make it unique.

What is wrong with both Extra White and Snowbound is not the Lightness, it is the Chroma.

White Duck has a Chroma over 7 and Snowbound and Extra white both have Chromas in the 2s

White Duck has a Hue of 91 - Extra White and High Reflective White are 117 and 108 - much greener and less yellow

If you are looking for contrast White Duck has a light value of 89 Snowbound is lighter with a light value just under 93. Extra White is a bit lighter at just over 94.

The goal here is to get something close to the same hue and chroma but lighter.

Westhighland White, Whitetail, White Flour are the ones I would test first if I had to choose SW.

I also included the LCH for my favorite White - Devine Color Icing. Almost as white as High Reflective White, with a spot more warmth to it.

Any Benjamin Moore store can mix it for you. Match of Devine Color™ V0101W Icing *

It is hard to depict colors on the internet, but this might help show how gray Snowbound and Extra White appear next to White Duck and show that Devine Icing is just a bit more yellow orange and less green than High Reflective White.

Hope this helps

What did you end up doing? I'm using White Duck in one room (closed floorplan home) and Snowbound is my trim throughout. Most of my walls have Shoji and Snowbound on them. But I wanted White Duck in one room. I feel the Snowbound works well enough with it. I don't think I would do the whole house with that combo though.
