Dulux Heritage 125ml Tester Pot Sky Blue

This 125ml tester lets you try Sky Blue – a mid-tone duck egg blue balanced between blue and green – on your own walls. Paint a patch on the wall you plan to decorate and check it at different times of day to see its undertones come through.

Dulux describe its undertones as blue and green, and suggest it for south- and east-facing rooms.

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.
