Blue Danube vs French Gray
Where Blue Danube belongs to Benjamin Moore's range, French Gray is a Farrow & Ball color. Blue Danube reads as blue, while French Gray reads as beige-greige — two distinct hue families, not close cousins. French Gray (LRV 43) reflects noticeably more light than Blue Danube (LRV 11), a difference of 32 points that becomes especially apparent in rooms with limited natural light. Blue Danube runs blue while French Gray is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 47.3, 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 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Blue Danube vs French Gray in Real Spaces
4 real rooms side by side. Seeing Blue Danube and French Gray 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. The LRV gap is large enough that French Gray will make the room feel meaningfully brighter than Blue Danube would.
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. French Gray returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Front Door
A front door is a focal point — small color differences read clearly at this concentrated scale. The LRV gap is large enough that French Gray will make the room feel meaningfully brighter than Blue Danube would.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. French Gray reflects noticeably more light off the walls, making the space read more open than Blue Danube.

5 simulated room previews — drag the slider on each to see Blue Danube on one side and French Gray 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.
