Colour matching powder coat to a brand guide, without surprises
Brand guides are written for print and for screens. Powder coat is a different medium with a different gamut, and the conversion between the two is where most colour arguments begin.
Why a brand colour is not a powder colour
Brand guides specify Pantone, CMYK or a hex value, all of which describe ink or light. Powder coat is a dry finish cured at 180 degrees and its colours are matched to the RAL chart or to a custom batch. The conversion is approximate by nature, and two suppliers converting the same Pantone will arrive at two powders that look close and are not identical.
The practical answer is to match against a physical standard rather than a code. Ask for a coated panel in the intended colour before the order, and approve the panel rather than the number. Where a brand guide must be followed to the letter, the panel becomes the reference and the code is written on the drawing as a note rather than as a specification.
Stock colours and what they cost
RAL 7016, 9005, 9016 and 7011 are stock items at most coating lines and add nothing to lead time. Everything else is ordered in, which adds one to two weeks and a minimum quantity, and that quantity is often enough for several hundred chairs whether the order needs them or not.
Where a room needs fifty chairs in a brand colour, the minimum powder quantity is the real constraint rather than the price per chair. Asking whether the colour is stock before the design is fixed is worth more than negotiating on the unit price afterwards.
Reading a colour difference
Colour difference is measured and expressed as a number, and the useful thresholds are these: below one unit the difference is invisible to the eye, two to three units is acceptable between batches and visible only side by side, and above three units is visible across a room in daylight.
Daylight matters. Workshop light is warmer than daylight and flatters a coat, so a colour approved under a workshop lamp can look wrong in a glazed room. Approve panels outdoors on a cloudy day, which is the most honest light there is, and keep the approved panel in a drawer rather than on a wall.
Keeping a top-up consistent
Three years after the original order, the same RAL code will produce a very slightly different powder, because pigment batches change. Side by side, that difference is visible even at two units. Where a room will be topped up, order the spare chairs with the original order and store them, rather than ordering later at the same code.
custom fast food furniture in a brand colour should carry the approved panel reference in the project file, not just the RAL number. made to drawing furniture that includes a colour note is easier to reorder than one that includes a code alone.
Where colour should not be spent
Frames take colour well and are the visible half of a room. Table tops in a brand colour are harder: laminate and compact panels come in a fixed decor range, and a printed top means a minimum order that rarely makes sense for one unit. Keeping the top neutral and the frame in the brand colour is the usual compromise and it ages better.
fast food furniture quality checks on delivery compare the batch against the approved panel under daylight, which is the only comparison that means anything. commercial fast food seating in a neutral frame with a branded top panel is the other way round of the same argument, and it is worth pricing both before deciding.
Keep one coated panel from the batch, labelled with the order number and the date, in the project file. It costs nothing at the time and it is the only object that settles a colour question in year four, when the code has been reinterpreted by a different powder supplier.
What buyers ask about this
Can you match a Pantone exactly?
No. Powder is matched to a sample panel and the result is close, never exact. Approving the panel is the honest process.
Is a custom colour much more expensive?
The powder carries a minimum quantity, so the cost per chair depends on the order size rather than on the colour itself.
How long does a custom colour take?
One to two weeks longer than a stock colour, added at the powder order stage rather than at coating.
What if the frame is scratched?
Touch-up paint in the same batch colour is supplied with the order. fast food chairs should ship with a small tin, and asking for one costs nothing.
