Krypton vs Upward
Both from Sherwin-Williams's palette. Krypton reads as blue-grey, while Upward reads as blue — two distinct hue families, not close cousins. Upward (LRV 57) reflects noticeably more light than Krypton (LRV 52), a difference of 6 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 3.9 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 8 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Krypton vs Upward in Real Spaces
8 real rooms side by side. Krypton and Upward 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 — Upward 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. Upward reads slightly lighter here — a subtle but real difference in how open the space feels.
Kitchen
In a kitchen, colors are seen under bright task lighting that amplifies undertones — what reads neutral elsewhere can show its hand here. Upward reads slightly lighter here — a subtle but real difference in how open the space feels.
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. Upward reads slightly lighter here — a subtle but real difference in how open the space feels.
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. Upward reads slightly lighter here — a subtle but real difference in how open the space feels.
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. Upward reads slightly lighter here — a subtle but real difference in how open the space feels.
Front Door
A front door is a focal point — small color differences read clearly at this concentrated scale. The brightness difference is modest but present — Upward gives the walls a little more lift.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. Upward reads slightly lighter here — a subtle but real difference in how open the space feels.

Krypton vs Upward Simulated Comparison
5 simulated room previews — drag the slider on each to see Krypton on one side and Upward 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.
