Mustard is a lighter, yellower colour; ochre is deeper and distinctly more orange-brown, reflecting its origin as an earth pigment.
Obvious difference: their hues sit about 27° apart, Ochre is 30 L* points darker. 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: Mustard reads warm, Ochre reads warm. 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 name a muted warm yellow, both are used for the same soft furnishings and paint colours, and neither is standardised — so a single velvet cushion can legitimately be sold under either name.
Mustard is a contemporary accent colour in interiors and knitwear, light enough to lift a scheme without weighing it down.
Choose it when: Choose mustard when the colour is an accent against a pale scheme and needs to stay cheerful and light.
Full mustard profileOchre is one of the oldest pigments in use and carries that association — it is the colour of natural iron-oxide earth pigments, and is used where a warm yellow should feel historic, rustic or grounded rather than bright.
Choose it when: Choose ochre when the colour needs depth and earthiness — against exposed brick, timber, stone or lime plaster, where mustard can look artificially bright.
Full ochre profileUsing a bright mustard where an earth-pigment colour is expected. In a period or rustic context the higher-chroma modern yellow reads as anachronistic, which is why heritage paint ranges tend towards ochre rather than mustard.
Placed directly against each other, Mustard and Ochre give a contrast ratio of 2.49:1 — 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.
