Blush pink is much paler and reads almost as a warm neutral; dusty rose is deeper, greyer and clearly a colour rather than a tint.
Obvious difference: they share essentially the same hue, Dusty Rose is 25 L* points darker, Dusty Rose is noticeably more saturated. These read as clearly different colours in ordinary viewing conditions, not as two versions of the same shade.

Where each sits on the two axes
Positions are plotted from each colour’s measured CIELAB values. The scale is perceptual, not a paint-mixing ratio.
Warmth: Blush Pink reads neutral, Dusty Rose reads neutral. Both sit on the same side of the warm/cool divide, so they will generally coordinate rather than clash, even where they are clearly different in depth.
Both are muted pinks marketed with the same soft, understated language, and both are used for the same purposes — so buyers expect them to be interchangeable and find they are not once the two are side by side.
Blush is used at scale: whole-room walls, bedding, and large upholstered pieces, where its paleness keeps it from feeling like a strong colour choice.
Choose it when: Choose blush when you want the warmth of pink without the room reading as pink, particularly in bedrooms and in rooms with cool light where a pale warm tint helps.
Full blush pink profileDusty rose is used where the pink should be visible as pink — accent walls, cushions and throws, knitwear, and bridal and event palettes.
Choose it when: Choose dusty rose when blush has proved too faint to register — it holds its identity in normal light and against pattern in a way blush does not.
Full dusty rose profileAssuming a pale pink will stay subtle across a whole room. Large areas of a pale tint intensify through inter-reflection, and a blush that looked barely-there on a chip can read as a definite pink once four walls are covered.
Pale pinks are among the colours most vulnerable to warm artificial light, which can push blush towards peach or make it look like a discoloured white.
A screen cannot predict how either colour will look on a real surface — see why colours differ between sample, wall and screen.
Placed directly against each other, Blush Pink and Dusty Rose give a contrast ratio of 2.14:1 — not enough for one to be used as text on the other at any size.
Contrast is only one part of an accessible pairing — see the accessibility guidance.
Measured differences (perceptual distance, hue, lightness, chroma, undertone) are calculated from each colour's own catalogue values. The usage and decision guidance is Colourwise editorial judgement drawn from conventional decorating and design practice, not a manufacturer claim — see /methodology.
