How to set global colors

[Vik88]

Good morning.

In Affinity Designer,  How do I create a global color to later modify it and have it automatically change in the image?

I create a global color, paint a bit in pixel mode, click on "edit color," but when I modify it, the change is not reflected in the image. How is this done?

Is there a way to generate and directly convert colors into globals based on an image?

 

Thank you, regards.

Pixels coloured with a Global Colour take on the colour as it was when the pixels were painted, there’s no way to change the colour automatically once painted. A pixel is just the colour it is, there’s no ‘back reference’ to a palette.

There may be other ways to do what you want to do but we would need more details.

Then, global colors is only for vectors?

Thank you

I would probably talk more about "objects", i.e. everything that has the property color.

You can use Global Colours in various places, such as recolouring an Image Layer with a Colour Overlay Effect, and the colour used will be ‘connected back’ to the Global colour.

But, once you set the colour of a pixel, that colour no longer has any ‘call back’ to the colour of the Global colour; it’s a ‘destructive’ modification to the pixel.
