Dockside Blue vs Extra White
Dockside Blue and Extra White come from the same Sherwin-Williams collection. Dockside Blue reads as blue, while Extra White reads as white — two distinct hue families, not close cousins. The 43-point LRV gap — 86 for Extra White vs 43 for Dockside Blue — means Extra White will open up a space more effectively. Where Dockside Blue leans cool, Extra White reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 24.5 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Dockside Blue vs Extra White in Real Spaces
2 real rooms side by side. Seeing Dockside Blue and Extra White 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
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. Extra White reflects noticeably more light off the walls, making the space read more open than Dockside Blue.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Extra White returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

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.
