Opinion? Don't break any Eggs
A wall of ANY color that has ANY sheen will reflect light, and Eggshell has a noticeable sheen.
The advice that was given was undoubtedly to avoid the dusty appearance and non-scrub-ability of a Flat, because any interior Paint whose sheen moves above Flat contains substantially more acrylic content, graduating upward to the Gloss level.
Here's a quick chart to illustrate.:
- Flat (0% gloss)
- Low Sheen *or Matte* (5-10% gloss)
- Eggshell (10–25% gloss)
- Satin (26–40% gloss)
- Semi Gloss (41–69% gloss)
- Gloss (70–89% gloss)
Not a lot of paint Mfg offer the "Low Sheen-Matte" range, preferring to jump from Flat to Eggshell, so many do in fact get advice from Pros to use Eggshell. Which is perfectly good advice for any normal use home. Flat White...or "Ceiling White" is used to hide surface defects, which occur more often on Ceilings because of less ability (...or costly effort...) by the Drywall Finishers. But Nix-ay on Flat for use on Walls...generally. Again, when it's used, it's done to "Cover" blemishes and hide application defects.
What make the difference between the ranges? A combination of the percentage of a "Binder" (usually Acrylic in a Water Based Paint ) as well as the initial Pigment content of a given Base.
The newer "Primer-Paint" that most all brands now offer have a preponderance of Acrylic content. Old style "Dead Flat" paint actually used Talc as a binder. Try to find a Talcum Powder that is either glossy or more solid in consistency!
The inherent "looseness" of a Flat painted surface so susceptible to abrasion...even wiping, but also makes it easier to touch up.
In Interior "Water Based" Enamels, the Acrylic content (...as shown in the chart above...) rises proportionately to the amount of Gloss added, which pertains to the degree of Sheen evidenced.
I always use Flat Interior Enamel for Wall and Ceilings, and "Oil Based" Eggshell for Trim. The latter for shear durability factors for Window/Door / Base Trim. Crown Trim can receive The same Flat treatment as the Ceiling.
Lastly. room color schemes are reversed for a Theater,with Light Base Trim / Ceiling -Darker Walls, changing up to Dark Base Trim - Darker Ceiling with a Wall color that usually falls somewhere in the Middle ranges. Now some still advocate Black (...really an ugly choice with 0% WAF ) and then do themselves the injustice by choosing a Dead Flat variety. There are higher quality "super saturated" Flat Blacks that themselves contain lots of Acrylics...and they do work better (still a Tomb-Like choice...) but they cost considerably more as well.
Leading us back to they type of Paint chosen being just as important as the Color...both being joined at the Hip as far as performance.
I'm done here.
