Hardie's ColorPlus palette has dozens of choices; in practice, a much shorter list dominates California installations. Here's what's actually going on the homes and what each looks like in our light.
Arctic White — the dominant choice
Arctic White is the single most-installed ColorPlus color on California Hardie. It's a clean warm white that reads correctly across architectural styles, ages cleanly under valley UV, and pairs with virtually any trim color. It's the safe answer that's also often the best answer.
Iron Gray and Aged Pewter — the modern direction
Iron Gray is a charcoal-toned medium gray; Aged Pewter is a slightly warmer mid-gray. Both read modern, work well with white or charcoal trim, and have been gaining ground steadily on modern farmhouse, contemporary, and updated ranch architecture. Iron Gray is the slightly darker, more dramatic choice.
Khaki Brown and Timber Bark — the warm earth tones
Khaki Brown is a warm taupe; Timber Bark a deeper warm brown. Both pair beautifully with foothill, wine country, and natural-context architecture. They age gracefully and read warmer than gray tones.
Boothbay Blue — the slate blue winner
Boothbay Blue is Hardie's most-specified blue in California — a soft slate blue-gray that reads architectural rather than trendy. Works on modern farmhouse, craftsman, and many contemporary directions. Pairs with warm white or crisp white trim.
Heathered Moss and Mountain Sage — the green direction
Heathered Moss is a soft warm sage; Mountain Sage slightly cooler. Both work on foothill, wine country, and traditional architecture where green reads as natural rather than aggressive. Less common than gray or blue but gaining ground.
Cobble Stone and Light Mist — the soft neutrals
Cobble Stone is a warm soft taupe; Light Mist a cool soft gray. Both work as 'almost-white' alternatives where pure white reads too stark. Gaining ground on modern minimalist and contemporary architecture.
Regional patterns we see
Sacramento Valley: heavy on Arctic White, Iron Gray, and Boothbay Blue across architecture types. Foothill: Khaki Brown, Timber Bark, Heathered Moss leading. Wine Country: warm cream and sage dominating. Tahoe: deep charcoals (Iron Gray, Pearl Gray) leading. Bay Area: full range with more modern direction (Aged Pewter, Light Mist) than Sacramento.
How to choose for your specific home
Sample boards in actual sunlight on the actual home — colors read differently in California light than on screen or in showroom. Look at samples at 9am, noon, and 4pm; the color shifts substantially. Test against existing trim if keeping it, against intended trim if changing. We provide physical samples as part of color consultation.

Yes — Hardie can be field-painted with any color; you trade ColorPlus warranty for color freedom.
