Choosing paint colour in South Florida light

Almost every colour regret we are asked to fix started in a shop. Somebody held a small card up under fluorescent lighting, liked it, and had five gallons mixed. On the wall it turned green, or pink, or simply went flat and disappointing in a way that is hard to name.

This is not a failure of taste. It is a predictable consequence of choosing colour in one light and living with it in another, and South Florida makes it worse than most places.

What the light here actually does

Daylight in Boca Raton is intense and it carries a lot of blue, particularly in the middle of the day when the sun is high. That blue cast pushes warm colours cooler and makes cool colours colder still. Then in the late afternoon everything swings hard the other way and goes golden for an hour.

On top of that, houses here are built to let light in. Wide sliders, large windows, double height spaces. That means more daylight hitting more wall, and it also means a lot of bounced light, which is the part people forget.

Bounce is the thing nobody accounts for

Light does not arrive at a wall only from the sky. It bounces off whatever is outside the window first. A lawn throws green up into a room. A terracotta pool deck throws warm orange. A screened pool cage in blue shade throws blue. A neighbour's yellow wall will quietly tint the room facing it.

This is why the same colour behaves differently in two rooms of the same house, and why a near-neutral grey chosen to be safe is the riskiest choice of all. Near-neutrals have very little colour of their own to anchor them, so they take on whatever the room gives them.

The sampling routine that works

• Sample on the actual wall, not on a card held against it. A card carries its own white border which tricks your eye, and the wall's existing colour underneath a thin sample will show through.
• Make the patch big. Two feet square at minimum. Colour reads differently at scale, and small samples consistently read lighter and more muted than the finished wall.
• Put samples on more than one wall in the room, including the wall opposite the window and a wall that gets direct sun.
• Look at it in the morning, in the middle of the day, and at night with your own lamps on. Three looks, minimum, and at least one of them after dark.
• Leave it up for a couple of days. First impressions of colour are unreliable and they settle.

That routine costs a few days and it removes almost all the risk from a decision you will be looking at for a decade.

Sheen changes colour, which surprises people

The same colour in a flat finish and in a satin finish will not look like the same colour. Higher sheen reflects more light directly back at you, which reads as lighter and slightly more saturated, and it also picks out every imperfection in the wall underneath.

In strong light, that matters more here than it does in a grey climate. A satin wall in a bright Boca Raton room can be genuinely uncomfortable to sit opposite. On the other hand, flat paint in a hallway with three children in the house is a maintenance decision you will regret in a different way. Sample in the sheen you are actually going to use.

Exteriors have their own rule

Everything above is more extreme outside, because there is nothing to soften the light. An exterior colour will read considerably lighter and brighter on the house than it does on a card, and dark colours take a genuine beating from ultraviolet over the years.

Sample exteriors on the elevation that gets the most sun, look at the patch at midday, and be honest with yourself about how it sits with the roof tile and the paver colour, neither of which you are going to change.

Ask for help, it is part of the job

One of our customers in Delray Beach wrote that the owner helped her choose the colours and she could not be happier. That is not an add-on service, it is part of doing the work properly, and it is a lot cheaper than repainting.
