Give the pattern's colours your own yarns and look at the designer's photos again - beta
Go to Settings → Assisted Features and switch on Colour Swatcher. It carries a BETA badge, and like every row on that screen it states what it sends before you agree to it.
Open a pattern and go to its Yarns tab - the Colour Swatcher sits there. On a project with a pattern linked, it is on the Pattern tab instead. Either way it starts by reading the pattern's colours, then paints its photos.
The pattern's colours are listed as Colour 1, Colour 2 and so on. For each one, Pick offers three ways to answer:
Your yarns - choose from the yarn you already own, so what you are looking at is a garment you could actually cast on tonight.
Photograph a yarn - point the camera at a skein and it takes the colour from the middle of the frame. Fill the frame with the yarn; if the middle is not clearly one colour it says so and asks you to try again.
… or any colour - a colour picker, for the yarn you are thinking about buying.
The photos are repainted in your colours, and you can open any of them fullscreen. Treat it as an impression, not a rendering: how close it gets depends on the photograph and on how clearly the pattern describes its colours. It shows you whether a colour scheme works, not what your finished garment will look like.
Show what was found reveals which parts of each photograph it identified as the garment - useful when a result looks odd, because it usually explains why. Look again asks it to have another go.
