This page is devoted to a single shade - Nightfall - and treats it the way a careful shopper would: first the color, then the wardrobe it belongs in, then the styles of boot it has been offered on, and finally how to look after it season after season. Nightfall is the mysterious one, a blue so dark it keeps its secret until daylight.

Nightfall is the darkest blue in the line - an inky blue-black that captures the last minutes of dusk. Where navy declares itself blue, nightfall keeps you guessing, and that ambiguity is exactly its elegance.
Nightfall is the evening boot of the collection. It slides under black trousers like a shadow, deepens monochromatic outfits, and pairs with metallics - a silver clutch, gold hoops - for nights when a brown boot would break the spell.
Nightfall has been used on classic short boots and fashion editions where a near-black blue is wanted, including styles with darker soles and trims that continue the twilight theme from top to toe.
Very dark suede shows lint and pale dust more than mid-tones, so keep a lint roller or soft brush by the door. Salt care matters in winter: brush marks out dry before they set into the nap.
This color's photograph dates from October 2017 and remains below as a historical reference point for Nightfall. For today's offering - which boots, in which colors, in which sizes - the official UGG website is the place to check.
Black is neutral-dark, navy is clearly blue in daylight, and nightfall sits between them: a blue so deep it only reveals itself in strong light or beside true black.
In most outfits, yes - it plays the same anchoring role with a little more depth. Beside a true black garment the blue undertone becomes visible, which most wearers find a feature, not a flaw.
It has appeared as a seasonal fashion color rather than a permanent staple, so current availability should be checked on the official UGG site.
