Thames Fog (LRV 27) reflects noticeably more light than Roller Coaster (LRV 23), a difference of 4 points that becomes especially apparent in rooms with limited natural light. The ΔE 4.9 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.

Roller Coaster vs Thames Fog in Real Spaces
5 real rooms side by side. Roller Coaster and Thames Fog 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 brightness difference is modest but present — Thames Fog gives the walls a little more lift.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. Thames Fog reads slightly lighter here — a subtle but real difference in how open the space feels.
Dining Room
A dining room lit by a dimmed pendant or candles is one of the most forgiving environments for paint — warm light softens almost everything. Thames Fog has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
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. Thames Fog reads slightly lighter here — a subtle but real difference in how open the space feels.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. Thames Fog reads slightly lighter here — a subtle but real difference in how open the space feels.

5 simulated room previews — drag the slider on each to see Roller Coaster on one side and Thames Fog on the other.
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.
