About Cascades
Cascades LRV and undertone
Sherwin-Williams Cascades (SW 7623) has an LRV of 4, placing it in the dark color range. Light Reflectance Value measures the percentage of visible light a surface reflects. At this low level, Cascades reflects little light, so its appearance can change considerably with room lighting. It belongs to the blue color family and has a calculated cool blue undertone. The listed hex value, #273E3E, also provides a digital reference, although screens cannot reproduce every paint color accurately. North-facing rooms generally receive cooler daylight, while south-facing rooms tend to receive warmer light. These conditions may alter how a cool undertone appears. Before painting an entire room, check a substantial sample beside trim and other fixed finishes.
Cascades in other brands
PPG Night Watch (PPG1145-7) is the closest listed alternative, with an LRV of 6 and ΔE 6.2. This value indicates that the colors are only similar, rather than close matches. Valspar Gotham Gray (4009-3) has an LRV of 4.69 and ΔE 9.9, showing a more noticeable measured difference despite its similarly low reflectance. PPG Pine Forest (PPG1134-7), at LRV 7 and ΔE 10.8, is also only similar. Benjamin Moore Wrought Iron (2124-10) has an LRV of 8.17 and ΔE 11.4, while Benjamin Moore Hale Navy (HC-154) has an LRV of 8.36 and ΔE 11.8. Both have higher reflectance and substantial color differences. ΔE 2000 provides a numerical comparison, but it cannot capture every change caused by lighting and paint sheen.
Lighter and darker Sherwin-Williams alternatives
Sherwin-Williams Iron Ore (SW 7069) has an LRV of 6 and ΔE 10.7, making it slightly lighter by reflectance but noticeably different in color. Cyberspace (SW 7076) shares the same LRV of 6 and ΔE 10.7, so the equal reflectance does not mean the two colors look alike. Naval (SW 6244) has an LRV of 4 and ΔE 10.8, matching Cascades in light reflectance while differing visibly in color. For a darker option, Tricorn Black (SW 6258) has an LRV of 3 and ΔE 11.3. Its lower reflectance may suit applications where a deeper finish is wanted. Compare samples against nearby whites, flooring, and furniture. Because very dark colors reflect little light, inspect samples in both natural and artificial lighting before choosing a wall or accent application.
