The deep ink navy has just the right amount of colour and depth to be universally useful and team with lots of colours already in your wardrobe.
I call this a “dead” colour meaning it acts as a backdrop or neutral for other colours – like a black or stone or charcoal. It doesn’t have enough cobalt blue colour to fight against other colours that you want to pair it with. It becomes a non-colour with a hint of blue but is a dark enough tone to be a very useful backdrop in a very sophisticated way.
It’s also what makes it versatile for both Summer and Winter outfits.
