A colour approval report is the document a mill or a factory receives back after submitting a lab dip (a small dyed sample) or a strike-off (a larger sample on the actual bulk fabric) for approval against the buyer's colour standard, the reference colour every sample is checked against. A colour approval report does not simply say "good" or "bad." It states one of three specific outcomes, and each outcome requires a different next action. A merchandiser or planner who reads only the word at the top of the report, without checking exactly which of the three outcomes it is, risks sending an instruction to a mill that skips a step the report never actually approved.
This lesson mainly teaches a decision: given a report's stated outcome, what should happen next. Reading a report correctly is a small skill with a large consequence, because the next action affects a full dye lot, and a dye lot at Colorline Dyeing is never smaller than 300 kilograms. Getting the outcome wrong does not just waste a little time; it can send bulk fabric into dyeing before the mill has actually met a condition the report itself stated.
You need: what a colour standard, a lab dip and a strike-off are, from lessons 4.3.1 and 4.3.2. If you have not read those lessons, the key terms below give you enough to continue.
By the end of this lesson you can:
Not covered here: why an approved colour can still look different under different light (lesson 4.3.4), and how a course of colour approvals is tracked across a whole bulk order (lesson 4.3.5).
| Term | Meaning |
|---|---|
| Colour approval report | The document stating whether a submitted lab dip or strike-off matches the colour standard, and what must happen next. |
| Conditional approval | The outcome stating the sample is close enough to proceed only after a specific stated adjustment is actually made. |
| Tolerance | The accepted range around an ordered value within which a measured result still counts as a match. |
| Shade match | Visual or instrument comparison of a fabric's colour against an approved swatch. |
| Dye lot | One batch of fabric dyed together in the same vat, which can differ slightly in shade or hand-feel from another batch of the same colour. |
A colour approval report never leaves its outcome open to guessing. It states one of three outcomes for the submitted lab dip or strike-off: approved, meaning the sample matches the colour standard within tolerance and the next stage can proceed as-is; conditional, meaning the sample is close enough to proceed only if a specific, named adjustment is actually carried out first; or rejected, meaning the sample does not match at all, and a new sample must be produced and resubmitted through the same approval step. Each of these three outcomes calls for a genuinely different next action, not three versions of the same "go ahead." Behind every outcome is a shade match, a visual or instrument comparison of the sample's colour against the approved colour standard; the report simply states, in words, what that comparison found.
| What can differ | The shapes you will meet | Why it matters to you |
|---|---|---|
| Approved | The sample matches the colour standard within tolerance. The next stage — strike-off after an approved lab dip, or bulk dyeing after an approved strike-off — can proceed with no further check. | This is the only outcome that needs no further action from the mill before proceeding. |
| Conditional | The sample is close enough to proceed, but only if a specific, named adjustment is applied first, for example "approved if darkened by about 2%." | The condition is a requirement, not a suggestion; skipping it sends an unapproved colour into bulk dyeing. |
| Rejected | The sample does not match the colour standard closely enough to proceed at all, with or without an adjustment. | A new sample must go through the whole approval step again; there is no shortcut adjustment that turns a rejection into a pass. |
| Reading the report correctly | Every outcome is written in the report's own words, not assumed from a general sense of "it looked fine" or "it looked close." | A planner who reads only the first word of a report, or relies on memory of a verbal update, can miss a stated condition entirely. |
Delta Garments does not only sew confirmed export orders like Order A. It also runs a hybrid production model, restocking its domestic customer, Cedar & Co., from its own Make to Stock line alongside confirmed orders. For a domestic reorder of Order A's own single jersey fabric, Colorline Dyeing has already produced and submitted a strike-off on the actual bulk fabric. The colour approval report comes back stating a specific outcome that Delta Garments' planner must read correctly before instructing the mill on what happens next — proceeding straight to bulk dyeing, or waiting on a stated condition first.
The worked numberOrder A's colour approval chain runs through several checkpoints before bulk dyeing, and each checkpoint can independently carry any of the three outcomes:
The lab dip against Order A's own colour standard was approved outright. The strike-off on the actual bulk fabric came back conditional, stating that the fabric must be darkened by about 2% before bulk dyeing. The bulk dyeing sign-off itself has not happened yet; it stays "in review" until the strike-off's condition is met and a new sign-off is submitted. Three checkpoints, three separate outcomes — none of them interchangeable with another, and none of them decided by what an earlier checkpoint on the same order happened to say.
A planner who only remembers "the lab dip was fine" and stops checking there would miss the fact that the very next checkpoint, the strike-off, carries its own separate outcome that must be read on its own terms. Each checkpoint's report is a fresh decision, not an update on the last one.
The methodA common mistake is reading "conditional" and hearing "approved." A conditional approval is not a pass. It states that the sample is close enough to proceed, but only once the mill has actually carried out the specific adjustment the report names — for example, darkening the shade by about 2%. Proceeding straight to bulk dyeing without confirming that adjustment was made sends an unapproved colour into a full-size dye lot, which at Colorline Dyeing is never smaller than 300 kilograms once it runs.
The same trap works in reverse with a rejection: assuming a rejected sample only needs a small, informal touch-up rather than a full new sample resubmitted through approval. Both errors come from the same habit — reading the outcome word without reading what it actually requires next.
This trap is easy to fall into precisely because "conditional" sounds close to "approved" in everyday speech, and a busy planner scanning a stack of reports can skim past the stated condition entirely. The safest habit is to treat every report as carrying two separate pieces of information: the outcome word itself, and, for a conditional outcome, the exact condition named beside it. Neither piece can be assumed from the other, and a planner who reads only the outcome word has read only half of what the report actually says.
A colour approval report always says one of three things: the colour matches, so go ahead; the colour is close enough only if a stated change is made first; or the colour does not match, so a new sample is needed. These are three different instructions, not three ways of saying the same "okay." A "conditional" report is not a pass. It becomes a pass only once the mill has actually made the exact change the report names, such as darkening the shade slightly. Skipping that change and moving straight to bulk dyeing sends an unapproved colour into a large, costly batch. Read every report's exact words, not just its first word.
The document the planner reads, exactly as it is written:
You are Delta Garments' planner. Can bulk dyeing proceed now? Decide before you open the answer.
No — bulk dyeing cannot proceed yet. The report's outcome is "conditional," not "approved," and the two facts that decide this are stated in the report itself.
First, the outcome word. The report does not say "approved." It says "conditional," which means the sample is only close enough to proceed once a specific change is made — it is not a pass on its own.
Second, the stated condition. The report names an exact adjustment: darken the fabric by approximately 2%. Nothing in the report says this adjustment has already happened; it is a requirement still to be met, not a note about what was already done.
Moving straight to bulk dyeing now would send fabric that has not yet been darkened by the stated amount into a full dye lot. Delta Garments' planner should instruct Colorline Dyeing to apply the stated adjustment first, then submit a new strike-off or sign-off confirming the condition is met, before scheduling bulk dyeing.
Colorline Dyeing does not run a dye lot smaller than 300 kilograms (its own fixed minimum), so this is framed qualitatively rather than as one fixed figure: skipping a stated condition and proceeding straight to bulk dyeing risks running that entire 300-kilogram-or-larger batch in a colour that does not actually match the standard, because the one adjustment the mill was told to make was never confirmed.
If that batch comes out wrong, the fabric cannot simply be relabelled as correct; it must be re-dyed or scrapped, and either outcome delays Cedar & Co.'s own restock date on top of the wasted dyeing cost. This lesson does not attach one fixed number to that outcome, since the exact loss depends on the batch actually dyed, but the risk is real every time a conditional outcome is treated as if it were a full approval.
Open the colour approval tracker linked at the top of this lesson. Its Tracker sheet lists an approval stage in each row, with columns for the date submitted, the date decided, and the status chosen from a fixed list: Submitted, In review, Approved, Conditional, or Rejected. Record Order A's own checkpoints exactly as they stand.
| Approval stage | Status | Next action |
|---|---|---|
| Lab dip 1 (Order A's own colour standard) | Approved | Proceed to strike-off. |
| Strike-off (bulk fabric sample) | Conditional | Confirm the stated adjustment is applied before bulk dyeing. |
| Bulk dyeing sign-off | In review | Wait for a decided outcome before scheduling. |

You now know how to read a colour approval report's three outcomes and take the right next action for each. The next lesson explains why an approved colour can still look different under different light, and what a merchandiser checks for before assuming a shade problem exists. Back to the course map
