Beside the three Cosmo threads closest to it, so the only thing changing is the colour.

Cosmo 668

Cosmo 668 is #2E2F52, RGB 46 47 82. The three beside it are the closest of the 500 Cosmo threads, measured the way the editor measures a colour match.

The same colour in DMC, Anchor and Madeira

Range	Code	Colour	How close	Distance
DMC	336	Indigo Blue	close	3.7
Anchor	941	Cornflower Blue Med	hard to tell apart	2.5
Madeira	905	Cornflower Blue DK	close	5.4

Each one is the nearest thread that range has, picked by measurement rather than read off a maker's conversion chart. The number is how far apart the two colours are on the scale the editor uses to match a thread to a picture; under 1 and nobody could tell them apart.

The colour on this page is our screen value for the thread, not the maker's. No thread maker publishes one, so every chart on the web is somebody's estimate, this one included. Use it to compare shades against each other, and buy from a real shade card.
