Glimmer vs Tidewater
Both from Sherwin-Williams's palette. Hue-wise, Glimmer belongs to the green-white family and Tidewater to the blue family. Glimmer (LRV 78) reflects noticeably more light than Tidewater (LRV 65), a difference of 13 points that becomes especially apparent in rooms with limited natural light. Both lean cool, so they'll behave similarly in mixed or changing light conditions. The ΔE 8.0 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Glimmer vs Tidewater in Real Spaces
2 real rooms side by side. Glimmer and Tidewater are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Living Room
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The LRV gap is large enough that Glimmer will make the room feel meaningfully brighter than Tidewater would.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. Glimmer reflects noticeably more light off the walls, making the space read more open than Tidewater.

Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
