Extract colors from a picture


In Celebration of plain weave (page 27) Annie MacHale explains how to extract colors from a picture to create a color palette.

I tried to add a basic function like this in Seizenn. (https://www.raktres.net/seizenn/).

Open the Palette tool and go down the page to

You first need to load a picture. You can get a random picture from unsplash.com with  or load your own picture with . If you use Seizenn on a smartphone, you can get access to your camera !

For example, with a random picture, you can get :

Then Seizen use two different algorithms to extract colors from this picture :

With the first button, you take all those colors to create a new main palette

But it could be tricky to find yarns with the wanted colors. So instead of getting all the colors in a new color palette, use the second button.

Imagine that you use this main palette (the default one) and that you have all those colors at home

When you click on the “filter” button, Seizenn will try to find de nearest colors in your main palette that will fit the colors from the picture. You then get

(Sometimes, if main palette quite poor, it chooses colors that doesn’t seem to be very relevant)

Clic on “Add colors…” to get those colors in your loom palette and remove colors you don’t want to use.

You are now ready to design a pattern inspired by your picture

Maybe not the perfect tool, but a first try to see if it would be useful for someone.



Seizenn interface evolutions – text buttons


The first version of seizenn (https://www.raktres.net/seizenn/editor.html) was created to work on desktop computers. When I began v2, I wanted it to work both on desktop and mobile devices and not to limit it to English speakers. I thought icons should help me for that two goals.

I received feedbacks saying the new interface was too disturbing.

As I continue to learn new programming things, I’m now able to adapt the new interface https://www.raktres.net/seizenn/

Now on top right of the screen there is a new menu :

  • the broken chain only appears when you are offline
  • clic on the icon with the profile to log. It’s red when you are not connected.
  • the third one shows if seizenn detect a desktop or a mobile device.
  • with the first checkbox, you choose if you want menu on the left of the screen or at the top
  • with the second checkbox you choose if you want to use icon or text button
  • use the selector to change language.

As an example, with the icon/text checkbox you can choose between


When you open Seizenn on a desktop, the tool uses text button on the left by default. On a mobile device, it uses icons on top. You can change as you want.

You may notice that I now use the new link https://www.raktres.net/seizenn/ for the new version in replacement of https://www.raktres.net/seizenn/v2/. The old version remains available on https://www.raktres.net/seizenn/editor.html

I hope those new evolution will help you.
