Dulux Heritage 125ml Tester Pot Light Cobalt

This 125ml tester lets you try Light Cobalt – a mid, floral blue with a slight violet undertone – on your own walls. Use this tester to see how it settles in your own light, from bright midday sun to softer evening light.

Dulux describe its undertones as blue, violet and grey, and suggest it for south-facing rooms. It works well in living rooms, bedrooms and kitchens.

Dulux Heritage testers are for use as a colour tester on interior walls and ceilings. Do not use as a touch-up paint. The full-size paint is a luxury washable matt emulsion, available tinted to order in 1L, 2.5L and 5L.
