Which costs of colour have actually been measured, and which are only explained?
Short answer
Fewer than the confident tone of most writing on the subject suggests. Of the 80 published statements Colourwise has recorded across 17 kinds of colour cost, 53 carry a figure, and only 18 of those (23%) are measured costs; the rest are list prices, warranty terms, payment allowances or market price gaps. 9 of the 17 cost drivers have at least one measured figure, and one has no figure of any kind. The counts describe what was found, not what exists.
Four kinds of evidence that should not be mixed
Every record in the dataset behind this section carries one of four tags. A measured cost is a quantity of money, material, labour or time that a source measured, compiled as a statistic or fixed in law: kilograms of plastic used to purge a mould, a duty per kilogram, a customs unit value. Documented industry practice is a rule, price list, warranty term or estimating allowance that a named body publishes and works to: it shows how the industry behaves, and a list price or a labour allowance is not a measurement of what the work costs. A market correlation is a price difference observed between colours in a market, which may or may not be caused by the colour. A Colourwise interpretation is our own reading and never carries a number. Most disagreement about what colour costs comes from quoting one kind as though it were another: a paint supplement as a production cost, a resale gap as an effect, a supplier's rule of thumb as a study.
What the matrix shows
The table on this page counts the records for each cost driver by tag. Overall there are 19 measured-cost records, 49 of documented practice, 8 market correlations and 4 interpretations. Documented practice dominates because that is what industries publish: reference documents, warranties, procedures and price lists. A measured figure exists for pigment and raw material; effect, metallic and pearlescent finishes; production changeover; small batches and minimum orders; print ink coverage; colour matching and rework; rejected batches and scrap; scarce and historic pigments; supply constraints and regulation. For coating complexity; speciality and spot inks; repaint and refinish; fade, replacement and warranty; stock complexity and inventory risk, the only figures are those of documented practice. For resale; packaging redesign and recyclate value, the figures are market price gaps. For brand colour consistency, the sources describe mechanisms and give no figure at all. These lists are generated from the records, so they change when a record is added or re-tagged.
Where the measured figures come from
The measured costs cluster where a public body had a reason to count. Geological surveys count minerals, so pigment raw materials have price series. Regulators set duties and estimate compliance costs, so supply constraints have figures. Environmental reference documents record solvent and paint quantities, so changeovers in paint shops have nominal values, and they include the occasional worked example in euros. A development project wanted to show dyehouses what re-dyeing cost them, so there is a dollar figure for rework in Bangladesh. One university laboratory weighed the plastic used to change a colour. Outside those cases, firms hold the data and do not publish it: no car maker reports what a special finish costs to apply, no insurer reports repair costs by colour, and no brand owner reports what holding a colour consistent across suppliers costs. The pattern is about who publishes, and it says little about which costs are large.
How the coverage figure is calculated
For each cost driver, count its observations by evidence basis and count those that carry a published figure. Measured-figure coverage = observations tagged 'measured cost' that carry a figure ÷ all observations for that driver, as a whole per cent. The best evidence available is the strongest of: a measured figure, a figure from documented practice, a market price gap, or mechanism only. The overall figure of 23% is 18 measured figures out of 80 records. Computed from the observation records in this dataset, each of which cites one source. No count is entered by hand, so adding or re-tagging a record changes the matrix. A record is one published statement from one source, so a long document that states five things contributes five records; the EU reference document on solvent-using industries is the largest single contributor, which is a reason to read the counts as a map of sources as much as of knowledge.
What the matrix cannot tell you
The counts describe what Colourwise found and recorded, not what exists: a driver with no measured figure may have one behind a paywall, in a language not searched or inside a firm. A driver with several records from one document is not better evidenced than its count suggests. Coverage says nothing about size; a well-measured driver can be a small cost. Read it as a map of where a cost claim about colour can be backed with a number and where it can only be explained. It is not a ranking of which colour decisions cost most. Two further cautions follow from how the records were gathered. The search was in English, of sources that could be read in October 2026, and several promising documents, among them estimating guides and some makers' technical sheets, were closed to non-subscribers or otherwise unavailable. And each figure belongs to its place and date: a duty in the EU in 2025, a price list in South Africa in August 2026, a dyehouse in Bangladesh in 2005. Counting them together says how much evidence there is and gives no licence to average them.

The four kinds of evidence, and what each does not show
Evidence basis
What it means
What it does not mean
Records
Measured cost
A quantity of money, material, labour or time that the source measured, compiled as a statistic or fixed in law, with its unit.
That the figure holds in another plant, country or year, or that it is the whole cost of the colour choice.
19
Documented industry practice
A rule, price list, warranty term, estimating allowance or process description that a named body publishes and works to.
That anyone measured the cost behind it. A list price is what is charged, and an allowance is what is paid, not what the work costs.
49
Market correlation
A price or sales difference observed between colours in a market, from listings, transactions or a survey.
That the colour caused the difference. Colour travels with model, grade, age and end market unless a study controls for them.

Colourwise interpretation
Colourwise's reading of what the cited evidence implies, labelled as such and never given a number.
A finding. It may be wrong, and the cited source does not state it.

How to check it yourself
For any claim that a colour 'costs more', ask which of the four kinds of evidence it is.
If it is a price (a paint supplement, a recyclate price), note the market and the month, and do not treat it as a cost.
If it is an allowance or a warranty term, note who publishes it and to whom it applies.
If it is a difference between colours in a market, look for what else differs between the things compared.
If no figure is given, check whether the source documents a mechanism or merely asserts one.
What the evidence says
Each statement is labelled by kind — established fact, a standard’s requirement, observed market data, a convention, or Colourwise’s own interpretation or analysis — with the strength of the evidence behind it.
Colourwise analysisModerate evidence
Of 80 recorded observations about the cost of colour, 53 carry a published figure and 18 of those are measured costs, a measured-figure coverage of 23%.
Based on: Counted by Colourwise from its economic-observation dataset: records tagged 'measured cost' that carry a figure, divided by all records. The matrix table on this page shows the count for each cost driver.
Caveat: Describes Colourwise's own dataset as of October 2026, not the state of all published knowledge; the tagging is Colourwise's judgement.
9 of 17 cost drivers have at least one measured figure, 5 have figures from documented practice only, 2 have market price gaps only and 1 has no figure.
Based on: Each cost driver is graded by the strongest kind of figure among its records, in the order measured cost, documented practice, market correlation, none.
Caveat: A driver graded 'measured' may rest on a single figure from one plant or one year; the grade says a number exists, not that it is representative.
The measured cost figures for colour come mainly from public bodies with a reason to count — geological surveys, regulators, environmental reference documents and a development project — and hardly at all from the firms that bear the costs.
Based on: Colourwise's reading of the sources behind the measured-cost records in its observation dataset.
Caveat: Reflects sources that were public and readable in English in October 2026; subscription data services were not consulted.
FactStrong evidence
The EU reference document on surface treatment using organic solvents, published in 2020, documents colour-related process mechanisms for vehicle coating, coil coating, furniture and several printing processes, with reference quantities and occasional cost examples.
Caveat: Its purpose is emissions control, so costs appear only where they illustrate a technique.
Why is a list price for metallic paint not a 'measured cost'?
Because it measures what a buyer is charged, which a seller sets for commercial reasons. The two price lists recorded here charge a flat sum for a short list of colours, and one waives it on a higher trim. Neither states what the finish costs to apply.
Does a cost driver with no measured figure cost little?
No. Brand colour consistency has no published figure of any kind in this dataset, yet it involves measurement, characterisation and approval work for every supplier. The matrix shows where numbers have been published, which depends on who had a reason to publish.
Can the figures in the matrix be added up or averaged?
No. They are in different units, countries and years, and belong to different processes. The matrix counts how many figures exist for each kind of cost; it deliberately does not combine their values.
