The floor finish is the reference
Judge Universal Khaki against your actual wood finish, not a generic wood species label. The starting material direction here is cream plaster and dark oak. Universal Khaki sits well below light beiges in reflectance, making a visible tan enclosure part of the choice.
Cream plaster can define that enclosure, while dark oak needs a separate shadow check so its shape is not lost.
Test the dominant wood color, not one grain line
Use Universal Khaki and Stone Lion to clarify the wood-floor choice against cream plaster and dark oak. Keep the sample edges touching the fixed material, and cover one color before judging the other. Near-neutrals can look noticeably different side by side; the final choice still needs to work on its own. Record the specific relationship you prefer, such as a clearer trim outline or a quieter connection to the floor.
Universal Khaki has an LRV of 40; Sherwin-Williams Stone Lion SW-7507 is 38. The difference is 2 points, with Universal Khaki returning more light under the reference measurement.
The condition for keeping Universal Khaki
Use its depth to define a room deliberately; compare a lighter tan before extending it through corridors. The undertones and neighboring colors covers that related choice.
Keep the Universal Khaki board vertical at the floor edge. A match to one pale grain line can misrepresent the dominant color across the installed floor. Judge the broad timber background from standing height. If the floor will be refinished, repeat the comparison with the approved new stain sample before ordering the wall paint. The coordinating color options covers that related choice. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
