A separate video for every colour — not a photograph
We filmed a separate product video for each of the 234 colours and linked it to the product page. When the customer taps a colour swatch, the video on the page switches to that colour. Not a square colour sample; real footage showing the flow of the paint, its coverage and how it looks once dry.
Why: the number one reason for returns is "this is not the colour I expected". Video settles that before the purchase — cutting both returns and support requests.
