I am trying to help my wife with such a question. It is required to replace all colors with others.
Watched this post-https://www.imagemagick.org/discourse-s ... or#p160403
but that's not my question.

  Version: ImageMagick 7.0.8-26 Q16 x86_64 2019-02-05 https://imagemagick.org
Is it possible to replace all colors at once?   For example with this palette.
gold on # ffbf66-this is background
green on # 08c5d1
red on # 00353f
blue on # 430c05
magenta on # d46f4d.

Although color and order is not important. I want to understand the principle itself.
And I would like the options for both versions IM.

You can use this general pattern:

Code: Select all

magick \
  in.png \
  -fill "#012345" -opaque "#234567" \
  -fill "#543210" -opaque "#654321" \
  out.png
This replaces all pixels of "#234567" with "#012345", and so on.

Never use JPG for this type of work unless you really have to, because JPG is lossy, and "solid colours" are not solid. If you must use JPG inputs, you will also need something like "-fuzz 5%".

I converted jpg in png. And only with the option "-fuzz 5%" everything worked fine.
Thank you very much.
