Choosing a color does not finish choosing the paint. A desired wall color can still leave two finishes on the shortlist, and their names alone do not explain what the maker actually declares. Benjamin Moore's Regal Select Interior brochure provides a bounded comparison of N549 eggshell and N550 satin/pearl. Its table can help organize the choice, but it cannot show how a real sample will look on your particular wall. Read the technical description and the visual preference as connected questions that need different evidence.
Keep the family and the codes attached
The brochure identifies eggshell as N549 and satin/pearl as N550. It groups both among the finishes used for high-traffic walls, hallways, closets, living rooms, kitchens and bathrooms. That shared category is important: the table does not divide these two into one finish for ordinary living rooms and another that is uniquely required there.
The document is the US brochure carrying the print code KW2/25 and copyright 2022,2025. Treat it as that identified family description, not a guarantee that every similarly named paint in another market has identical instructions. For the actual order, retain the product code and finish as well as the desired color identifier.
Imagine choosing a color for a reading room with one side window. The first useful result from the table is that both shortlisted finishes occupy the same broad declared wall-use group. That narrows the remaining conversation: the room description alone has not selected a winner between them. It also prevents a retailer's shorthand recommendation from being mistaken for a distinction explicitly made in this table.
Do not turn unlike measurement angles into a simple score
The eggshell entry gives a gloss/sheen range of 15 to 22 at 85 degrees; satin/pearl gives 20 to 30 at 60 degrees. The measurement angle is part of each entry. Subtracting the first number of one range from the first number of the other would discard that difference in measurement conditions.
The practical interpretation is modest: the maker describes distinct finishes and reports their readings under stated geometries. These entries do not supply a personal attractiveness score or prove how much brighter one wall will appear beside the other in your room. Preserve the full figures when asking the maker to explain them instead of reducing both to unlabeled numbers.
For a room sample, write down what you actually want to judge: the appearance near the window, the view from the reading chair and how the surface looks under the evening lamp. Those are proposed observations for the eventual sample, not results established by this article. No paint sample or finished room was inspected for this comparison.
Let the sample answer the question the table cannot
The brochure itself says printed colors are not exact matches and strongly recommends paint sampling before use. A screen image of the color therefore should not become evidence that a chosen finish has already achieved the desired room effect. Ask the supplier for an appropriate way to compare the actual shortlisted products, following their instructions.
Keep two lines in the decision note: declared product/use information, and observed sample preference. If one remains unresolved, leave it unresolved rather than writing suitable and beautiful as one combined conclusion. The actual order should state the precise color, product and finish that were agreed, not merely repeat the room name.
This approach can end with either finish, or with a request for another appropriate product. Its value is a decision whose reasons remain visible: the family table supports the declared-use comparison, while the actual room sample supports a visual preference that a brochure cannot make on the reader's behalf.
