doing some graphic work on my linux box: how-to!?

#1 Post by p1e »

good evening dear MX-Linux experts, :happy:

...hope youre all right and everything goes well at your site:


today - i ve got a topic that is concearned not directly to linux but to GIMP or - hmm Krita or inkscape.. (probably)

well i ve got a topic : "how to recolor an certain thing on with some of the above mentionend packages?" - or - if that does not work - with GIMP itself!?


well i guess that i could do some minor changes to the color of an image in - is this Right?
well on my notebook i run MX (and i am glad to do so)- and i am very fine with that: i have to admit : i am loving it!

That said: - hmm i guess that we have multiple Options here to do that: we could make use of (some) various tools and techniques, including the so called "Colorize" filter, or besides that the so called "Color Exchange" filter!?
Or if that all does not function - we are able to even make use of the so called "Fuzzy Select" tool in combination with other tools for more targeted changes.

Hmmm - these tools allow uns to adjust the hue, saturation, and lightness of specific colors or areas within the image.

Well i think thats the best thing to write down some of the according methods and techniques a breakdown of common methods - that way i can learn these things. Please have a closer look at the writing - and if some thing does not fit
very well here - just inform me - so that i can correct the stuff - add more and better things and keep on with good and learned stuff here:

here some ideas that i think, they should work:.

1. Colorize Filter:

"Selection:" First, we ought to select the area of the image we want to recolor using tools like the Fuzzy Select (Color Select) tool or the Free Select ( sometimes its called the "funny" Lasso) tool.
"Colorize:" now we need to have to go to Colors > Colorize: This step is important and it opens a dialog box where we can adjust the hue, saturation, and lightness to achieve the desired color we wanna have here.

2. Color Exchange Filter:
afaik we can use the so called "Select Source Color" Option too: Therefore we may use the Color Exchange filter by going the way down in the menu (Filters > Enhance > Color Exchange) to specify the certain color we want to replace.

....and - very important - afterwards - we could use the so called "Select Target Color"-method: with that we can choose the new color we want to use as a replacement. After all we can use the "Adjust Range" and do a "Fine-tune" of the color range using the "From" and "To" sliders to ensure the filter only affects the intended colors.

by the way: see the image - i want to change the background:

see the image: https://imgur.com/a/HZsKXTA

which method would you apply here !?


and sorry once again - i wrote it down since this method is helpful for me: Only in the act of writing for me thoughts take shape, connections become apparent, and previously unimagined insights emerge. This is how knowledge is generated through writing.


look forward to hear from you

yours p1e

This is a large topic and there are MANY factors that can influence the method that works best. It IS all about the image.

What seems to work the best for me... ( or stated a little differently - what I seem to like the best?)... is using the gimp color selector tool and then selecting the color you want to change and then change it using the paint tool. HOWEVER .. you MAY have to just use the Fussy Select Tool as the Color Selector will work across ALL of your selection with that color.

The best method to use on one image / color... may not be the best on another.. so my suggestion is to learn how / what each selection tool does - and then be prepared to try different ones based upon the image / color your attempting to change at that time.

Sometimes, I find it best to duplicate a layer, over lay it and color THAT layer and then 'meld' the two layers together...

good answer charles.

make a copy or three and try tweaking with different tools and filters etc. i loved photoshop and even their cheaper Photoshop elements. 90% of the full version. it was easy and user friendly. Gimp - i use but still do not get the hang of it. i also used krita - i like that too.

i am probably wrong - but i have understood krita to be used for a different type of pic creation and format and rendering.

either take notes which can be tedious based on your trial and erros or else have a great memory - easier.

Thanks.. and yes on the notes! .. I tend to create a working folder, and then tend to "spawn off" my major versions as I go. (Save as, etc) and its not uncommon for me to have 30 to 40 files of various stages in doing colorizing or mods like this.

Typically I start down a path and have four or five versions of that method. Then start again on another path etc.. Using this method I can compare, work around or even blend them - it takes time.. practice and patience!

In an attempt to wean myself off of Photoshop and the Photopea workalike website, I tried forcing myself to use GIMP and found the process awkward and unpleasant. Fortunately, there's a massive patch called "PhotoGIMP" that singularly reconfigures the keyboard shortcuts and visual layout to make it easier for users who are more accustomed to Photoshop to use it without having to relearn a lot of things that Adobe has turned into muscle memory.

The image is just circles and lines. For me it would be quicker to redraw it in inkscape rather than messing about with pixels in gimp. You of course first need to get over the learning bump of how to use whatever programme you choose.

In gimp I would try selecting the background colour (play around with the sensitivity to include more or fewer adjacent pixels), invert the selection (ie. have the circles and lines selected), copy and paste that selection to a new layer, create another new layer and fill it with desired background colour, and then see how many stray pixels from the circles and lines need to be touched up.

In general, everything depends on the quality of the original image and your requirements for the edited image.
