Blue Grotto vs Hyper Blue
Both from Sherwin-Williams's palette. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. Hyper Blue (LRV 10) reflects noticeably more light than Blue Grotto (LRV NaN), a difference of NaN 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. With a ΔE of NaN, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below you'll find 10 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Blue Grotto vs Hyper Blue in Real Spaces
10 real rooms side by side. Seeing Blue Grotto and Hyper Blue in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
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. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. The distinction reads clearly at room scale, making the choice between them concrete.
Kitchen
In a kitchen, colors are seen under bright task lighting that amplifies undertones — what reads neutral elsewhere can show its hand here. The distinction reads clearly at room scale, making the choice between them concrete.
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. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.
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. The distinction reads clearly at room scale, making the choice between them concrete.
Home Office
The test for a home office color isn't how it looks in a quick glance — it's whether it still feels right after a full day of work. The distinction reads clearly at room scale, making the choice between them concrete.
Mudroom
Mudrooms are seen in passing, often under whatever light comes through the door — a context that favors colors with some depth. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.
Patio
Outside, paint color competes with sky, landscaping, and direct sun — all of which shift how both of these read compared to an indoor chip. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.
House
Seen across an entire facade, subtle tonal differences become pronounced. What reads as nearly the same on a chip often reads as clearly different at scale. The distinction reads clearly at room scale, making the choice between them concrete.
Front Door
A front door is a focal point — small color differences read clearly at this concentrated scale. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.

Blue Grotto vs Hyper Blue Simulated Comparison
5 simulated room previews — drag the slider on each to see Blue Grotto on one side and Hyper Blue 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.
