I'm not talking about white here, or grey, or bland. Call it a minor distinction but there is such a thing as cold pastels. Not quite devoid of colour, cold pastels are pastel tones that have just a smidgeon of pigment - but not warm pigment like pink or beige, but an altogether cooler variation. It's the matt finish that makes these colours still seem like 'pastel' colours, at least in my eyes.
