Our blue is a rich, deep ocean blue with a subtle teal undertone — clearly and confidently blue. It's brighter and more vivid than our Midnight Blue, and has far more blue presence than our Teal.
The classic blue, done properly
Blue is the Goldilocks of our darker shades — deep enough to feel rich and forgiving between washes, bright enough to still read clearly as colour. It works with almost any bedroom, from crisp modern white to traditional or coastal styles. One customer, comparing it to a pillowcase from an American brand, put the practical case simply:
"I'd previously bought a silk pillowcase from an American company but had issues with the sizing — it was too small for my pillow. This one is a perfect size, and a beautiful dark teal colour. Lovely and soft, and great for my hair and skin."

The one people buy six of
Blue's reviews are full of repeat buyers — and one of them has given our zip and our dye a four-year field test we couldn't have run ourselves:
"Just added another two to my collection — six and growing! I love the dark colours, they are rich, luxurious and don't fade. The zip is well concealed and going strong after four years of hard wear on my first pillowcase. My hair's less frizzy and I don't need to iron the creases out of my face anymore!"
Verified buyer — Midnight Blue Silk Pillowcase
"This is the third silk pillowcase I have purchased and it is as lovely as the others."

Care instructions
Turn inside out before washing
Machine wash 30° cool/delicates programme
Silk detergent only — we recommend Ecover Wool & Silk
Tumble dry on a low heat only
Or dry flat, away from direct sunlight
Iron inside out on cool/silk setting
Avoid detergents containing optical brighteners, bleaching agents, or enzymes — with deep shades like blue, brighteners are the quickest way to dull the colour.
