Which tool fits my question?

You are looking for a specific thread colour or want to know which number belongs to a shade: the colour chart shows all colours at a glance, searchable by number, name and colour group.

You have one colour and need a second that works with it: the colour finder suggests similar shades, contrast colours and harmonies, and shows how well a thread stands out on different fabric colours.

You have a finished embroidery file and want to check size, colour order and density before sewing: the embroidery file viewer opens PES, DST, JEF, VP3 and more right in your browser.

Frequently asked questions

Are the tools free?

Yes. All tools run directly in your browser, with no account and no sign-up.

Which threads do the colour chart and colour finder cover?

Madeira Polyneon 40 Classic. Each colour also lists the matching Polyneon Green number.

How accurate are the colours on screen?

Screens show colours differently, and thread has a sheen no pixel has. The HEX codes are a guide. For the final choice, a real thread card or a test sew-out is more reliable.

Which embroidery files can the viewer open?

PES, DST, JEF, VP3, EXP, XXX, HUS and PEC, the formats of Brother, Tajima, Janome, Husqvarna Viking, Pfaff, Bernina, Melco and Singer. The file is read only in your browser and is not uploaded.
