Algorithm is a pale off-white from COAT. As a premium paint, it’s a popular colour to seek out close matches and value-brand alternatives to.
Orchid Mist by Johnstone's is the closest match from any other brand (near-identical) — and it holds Algorithm’s lightness, warmth and saturation alike. It’s also the best-value tier of the close matches — unusual, as the nearest match and the best-value one usually differ. Every other brand has a near-identical match, so you have plenty of choice here. LRV is estimated from each brand’s swatch, so order testers before committing.
Below is every genuinely close match to Algorithm from the other eight brands — ranked purely by closeness, so where one brand has several near-misses, they all appear. For the single best match per brand, see the Algorithm colour page.
The nearest Dulux colour is Rail Cloth (near-identical). It won’t be pixel-perfect, so order a tester before committing.
Of the close matches, Orchid Mist by Johnstone's is the best-value option (value, near-identical).
The list shows every genuinely close match from other brands, ranked nearest-first by perceptual colour difference — including several from one brand where they’re all close. Screens differ from paint on a wall, so treat these as a shortlist and always order tester pots.
