Flexa's Let's Colour campaign by Etcetera used custom T-shirts at Amsterdam's Color Run to reveal the brand's logo as runners accumulated coloured powder.
How Flexa Turned the Color Run Amsterdam Into a Living Brand Statement
Flexa's Let's Colour campaign is an ambient activation created by Amsterdam-based agency Etcetera in July 2013, in which custom-fabricated white T-shirts worn by Color Run participants progressively revealed the Flexa logo and brand payoff as coloured powder accumulated during the 5K race, turning each runner into a live, evolving brand medium across the streets of Amsterdam, in The Netherlands.
The Color Run had already become a global event property by the time its Amsterdam edition launched in 2013. Prior editions had taken place in Hawaii, San Francisco, and Berlin, among other cities, before the event reached The Netherlands. The race is untimed, according to Clapboard, and participants begin dressed entirely in white before being doused in coloured powder at stations along the route — a format that made it an unusually natural environment for a paint brand to operate in.
Flexa, the leading paint brand in The Netherlands and part of AkzoNobel's decorative paints portfolio, used this setting with structural precision. Rather than purchasing conventional event sponsorship signage or distributing branded merchandise in the standard sense, Etcetera engineered a T-shirt whose design was latent at the start of the race and only became legible as colour built up across the fabric. The Flexa logo and the campaign payoff — Let's Colour — emerged gradually, mirroring the brand's core proposition about colour transformation. The activation required no media buy beyond the event itself. It operated entirely within the lived experience of participants, making it a textbook example of ambient advertising in the consumer durables category in the 2010s.
The campaign sits within the industrial and lifestyle registers simultaneously, connecting a functional paint brand to the joy, movement, and shared energy of one of Amsterdam's most photographed public events of that year.
Flexa occupies the leading position in the Dutch decorative paint market, a category defined by considered purchase behaviour and low spontaneous engagement. The strategic challenge for any paint brand in The Netherlands is converting a product associated with domestic labour into something aspirational and culturally visible. The Let's Colour platform addressed this by locating Flexa inside moments of colour-led joy rather than home improvement contexts.
The paints and coatings market globally was estimated at approximately €80 billion in 2013, according to AkzoNobel's own published materials, with decorative paints representing approximately 42% of that total — roughly €33.6 billion — also according to AkzoNobel. The broader industry had achieved 5.4% average annual growth over the preceding decade, as reported by the World Paint and Coatings Industry Association. AkzoNobel's 2013 investor materials projected growth of approximately 3 to 4% for relevant paints and coatings sectors, characterising decorative paints specifically as having limited near-term overall growth, according to akzonobel.com. In The Netherlands, this translated into a mature, competitive market in which share is fought at the level of brand perception rather than category expansion.
Competitors such as Dulux, also an AkzoNobel brand operating in adjacent markets, and Sikkens pursued more conventional above-the-line messaging during the same period. Flexa's decision to invest in a precisely engineered ambient execution at a mass-participation event in Amsterdam reflected a sharper understanding of where Dutch consumers were directing their attention in the early 2010s. The Color Run's untimed, non-competitive format, as noted by Clapboard, attracted a broad demographic united by a willingness to participate in public colour spectacle — a psychographic that maps directly onto Flexa's Let's Colour brand positioning. Etcetera's strategic bet was that the right product, worn by the right crowd, in the right environment, would generate more meaningful brand impact than a media spend of equivalent value.
Etcetera fabricated a T-shirt that functioned as a time-based creative medium. The garment began the Color Run race in Amsterdam as a plain white item of clothing with no visible branding, and ended it as a fully legible Flexa advertisement — rendered not by printing or embroidery but by the natural accumulation of coloured powder during the 5K event.
The creative team responsible for the execution included creative directors Peter van Leeuwen and Ben Imhoff, with creative work by Vanessa Burgmans and Billy Witbraad, according to Clapboard's production records. Campaign management was handled by Marie-Louise Diekema, account contact was André Koster, and social media strategy was led by Mark de Leeuw, also according to Clapboard. The production record documents one media asset associated with the campaign, consistent with a focused ambient execution rather than a broad multi-channel rollout.
The craft challenge was precise: the logo and payoff had to remain invisible on a white background at the start and become legible only after sufficient powder had been absorbed. This required both material engineering — selecting a fabric weight and weave that would catch and hold coloured powder in a controlled way — and typographic decisions about how the brand mark would render at the point of maximum colour saturation. The creative concept collapsed the gap between the product category and the event experience entirely. A paint brand asking people to add colour to their world found its message literalised on the bodies of hundreds of Amsterdam participants over the course of a morning. The ambient format, used here in its most formally rigorous sense, made the medium and the message structurally identical. For a consumer durables brand operating in The Netherlands in 2013, this represented an unusually sophisticated alignment of channel, context, and creative form.
No verified performance data for the Let's Colour campaign by Flexa and Etcetera is publicly available. No independent figures for participant reach, earned media coverage, social amplification, or brand tracking movement in The Netherlands following the July 2013 activation have been documented in publicly accessible sources. Analysis here therefore addresses structural effectiveness rather than reported outcomes.
The campaign's core mechanism — a T-shirt that reveals branding only through participation — creates a closed loop between consumer action and brand communication. Every runner who crossed the finish line in Amsterdam wearing the Flexa shirt became a verified touchpoint: the more colour they accumulated, the more visible the brand became, meaning engagement and exposure were causally linked rather than assumed. This is structurally sounder than most event sponsorships, where brand presence is peripheral to the experience rather than embedded in it.
The choice of The Color Run as the activation venue was also structurally efficient. The event's heavy social documentation culture — participants routinely photograph and share their powder-covered appearances — created organic secondary distribution for any branded element present on participant clothing, without requiring a paid social layer. The campaign's single documented media asset suggests Etcetera designed for depth of experience over breadth of impression, a defensible trade-off for an ambient execution in the consumer durables category in the early 2010s.
Clapboard rates the Let's Colour campaign by Flexa at 63 out of 100, reflecting strong conceptual alignment between brand proposition and activation format, with limited documented evidence of scaled impact beyond the Amsterdam event itself.
Flexa's Let's Colour was an ambient campaign created by Etcetera in July 2013.

Etcetera created the Let's Colour campaign for Flexa. The Amsterdam-based agency produced the activation for the 2013 Color Run in The Netherlands. Creative directors were Peter van Leeuwen and Ben Imhoff, with creative work by Vanessa Burgmans and Billy Witbraad, according to Clapboard's production records.
Flexa's T-shirt began the Color Run entirely white, with no visible branding. As runners accumulated coloured powder during the Amsterdam 5K, the Flexa logo and Let's Colour payoff became progressively legible on the fabric, making brand visibility a direct function of each participant's colour exposure during the race.
Flexa chose the Color Run because its powder-colour format directly mirrored the brand's Let's Colour proposition. The untimed, participation-led event in Amsterdam attracted a broad Dutch audience engaged in public colour spectacle, according to Clapboard, making it a structurally ideal environment for a leading Netherlands paint brand.
Clapboard rates the Flexa Let's Colour campaign at 63 out of 100. The score reflects strong conceptual alignment between Flexa's brand proposition and the ambient activation format, alongside limited publicly documented evidence of scaled impact beyond the Amsterdam Color Run event itself in July 2013.
