Why your DST file shows the wrong colours

A DST file can contain the correct stitch path and still open in completely different colours. DST does not store the actual thread colour values. The viewer has to provide a placeholder for each colour block.

Stitch order and thread colour are separate

The machine follows the recorded needle movements and stops for colour changes. Which thread is loaded at each stop is a production decision. A green placeholder in the viewer cannot tell you whether the designer intended black, blue or another shade. Changing that placeholder affects the preview; it does not change where the needle goes.

Use a matching colour file or colour sheet

  1. Open the design in the DST file viewer.
  2. If the designer supplied COL, EDR or INF, add that companion file after the design or select the files together.
  3. Compare the colour-block order with the designer's sheet. A companion file from a different revision can assign the wrong colours, even if its name looks similar.
  4. When no companion file is available, click the thread-colour swatches and assign each block from the sheet.
  5. Play the sequence to check that the colours occur on the expected shapes.

Use the thread brand and catalogue number on the production sheet when buying or loading thread. Screen colour is an approximation: displays, thread materials and lighting can change its appearance.

Keep the production information together

Save a PNG preview and CSV thread list from the inspector. Keep these beside the original DST when handing the job to an embroidery shop. Include the final design dimensions and the intended colour order. If you cannot identify a colour block, ask the designer instead of guessing from the placeholder palette.

Would PES solve this?

PES can include thread-colour information, but it must also be compatible with your machine. Read PES versus DST before choosing an export. EmbroViewer currently views both formats; it does not convert an existing DST into PES. Its converters create DST or PES from vector SVG artwork.

A corrected digital palette does not prove a design will sew cleanly. Check jumps, dimensions and stitch order, then use a test sew-out for production. The pre-sewing checklist explains which checks a preview can and cannot provide.

Frequently asked questions

Is my DST corrupted if the colours look wrong?

Different preview colours alone do not establish corruption. DST lacks actual thread colour values.

Does changing the preview colours rewrite the DST?

No. EmbroViewer remembers colour choices locally and can export a preview and thread list; the original DST is unchanged.
