From the trade
Paint Hague Blue and your chosen match on two boards in the same finish. A flat and an eggshell in one colour never look identical.
Check them on the darkest wall in the morning and again under your own lamps at night. That is where small differences show.
Give the merchant the brand, colour name and code shown here. It avoids the guesswork of a scanned match.
In your light
Pick the way your window faces and the time of day. The same paint can look like three different colours.
North light is steady but cool and grey. It pulls blues and greys colder and makes greens look heavier. Warm based colours hold up best.
An approximation of how light colour and strength shift a paint. Use it to narrow a shortlist, then paint a sample board and look at it at these same times.
Building a scheme
Worked out from undertone and depth, the way a decorator would put a scheme together. Paint samples side by side before you commit.
A pale colour from the same undertone as Hague Blue, so the ceiling does not look stark white against it.
One step lighter or darker on skirtings, doors and window boards. A tonal scheme is the easiest way to make a room feel finished.
From the other side of the colour wheel, at a similar depth, for a door, a bookcase or a cushion. Use in small amounts.
