Why Is a Colour Trending? How Fashion Forecasting Works
How fashion colour trends are forecast 18-24 months ahead by Pantone and WGSN, and why brands must plan fabric sourcing before a colour trend hits retail.
Why Is a Colour Trending? How Fashion Forecasting Works
Every season, a handful of colours seem to show up everywhere at once — on the runway, in retail windows, and across social feeds. To a buyer or designer planning a collection, this can look like it happens overnight. It doesn't. A trending colour is usually the visible end point of an 18-to-24-month forecasting process run by dedicated colour agencies, colour councils, and in-house teams at fashion houses, long before the fabric is even dyed.
For fashion designers and garment and fabric buyers, understanding this pipeline isn't academic — it decides how early you need to lock in a colour story, how much lead time your dyehouse needs, and whether you catch a trend at retail or arrive after it has already peaked. This piece breaks down who forecasts colour, what actually drives a colour into "trending" status, how long the process takes from forecast to shelf, and why sourcing fabric ahead of the curve — not reacting to it — is what separates brands that sell through from brands stuck discounting.
Who Decides Which Colour Is "In"?
Colour trends aren't guesses — they come from a small set of specialised forecasting bodies whose job is to track colour data years ahead of the season:
- Pantone Color Institute — runs the best-known process in the industry, scanning entertainment, art, fashion collections, socio-economic conditions and major cultural moments to select an annual Color of the Year, typically announced each December for the following year.
- WGSN, working with Coloro — combines a proprietary colour-tracking algorithm (which scans runway shows, retail assortments, street style and social platforms) with human forecasters to publish seasonal Key Colours and a joint Colour of the Year, released roughly two years ahead of the season they apply to.
- Fashion houses' own design and colour teams — interpret these macro forecasts into their own runway palettes at fashion weeks, which forecasters and buyers then read back into the next round of predictions.
- Regional colour councils and trade bodies — adapt global forecasts for local market tastes, festivals and buying calendars, which matters enormously for a market as colour-driven as India.
What Actually Drives a Colour Into "Trending"
No single runway show or celebrity outfit makes a colour trend on its own. Forecasters weigh several signals together before a colour earns a place in a seasonal palette:
- Runway influence — colours repeated across multiple designers' collections at the same fashion week season carry far more forecasting weight than a colour seen on just one show.
- Cultural and economic mood — forecasters read broader sentiment (optimism, caution, escapism) and translate it into palette direction, which is part of why muted, grounded tones tend to surface in uncertain economic periods and brighter, saturated colours return when confidence rises.
- Social media signal — platforms are now tracked as a real-time data source, showing forecasters which colours are gaining organic traction with consumers well before they hit mainstream retail.
- Sustainability considerations — as brands face pressure on dye and water use, forecasters increasingly weigh which colours are achievable with lower-impact, scalable dyeing processes alongside their aesthetic appeal.
- Retail sell-through data — what actually sold in the previous season feeds back into the next forecast, so a colour that performed well at retail is more likely to be extended or built on.
The Lead Time Between Forecast and Retail Shelf
This is the detail most buyers underestimate: forecasting agencies are not calling trends for the season about to start — they are calling them for seasons well into the future.
- WGSN and Coloro publish seasonal Key Colours and Colour of the Year picks roughly 18 to 24 months ahead of the retail season they describe, so the palette a shopper sees on a rack this year was forecast the better part of two years earlier.
- Pantone's annual Color of the Year is announced months before the calendar year it names, giving brands, packaging, and product teams a runway to build around it before consumers see it everywhere.
- Between forecast and shelf sits the real production chain: yarn and greige fabric sourcing, lab-dip approval, bulk dyeing, printing, cutting, and garment manufacturing — each stage adding weeks that a brand cannot compress once a trend has already gone mainstream on social media.
Why Fabric Sourcing Has to Move Ahead of the Trend, Not With It
By the time a colour is visibly "trending" in stores or on social feeds, the forecasting and production window behind it has usually already closed. That has direct implications for how a brand should plan fabric sourcing:
- Lab-dip development and colour-matching against a forecasted shade takes real time — this needs to start while the colour is still a forecast, not once it is confirmed at retail.
- Bulk dyeing and digital printing runs need committed fabric orders and minimum quantities locked in early, which is only possible if the colour direction is decided ahead of the season.
- Brands that wait for a colour to prove itself at retail are, by definition, sourcing after the window — they end up competing for the same dyehouse capacity as everyone else reacting at the same time, with less room to negotiate on price or MOQ.
- Working from a forecasted colour story instead lets a brand pre-book fabric in the right base cloth and get ahead of capacity constraints, rather than scrambling once a shade is already selling out elsewhere.
