Oldschool Shirt Designs / Threshold Question - CrystalLogic - 04-11-2021
Hi!
I am new to this forum and have a specific question. I tried to find the answer myself by experimenting but now came to the conclusion i need external help.
I am relatively new to GIMP (watched and worked through one or two dozen of tutorials, experimenting, some of this , some of that) and really enjoy it. What i would really like to do is trying to create shirt designs, namely pretty specific ones. I try to explain:
In the music genre where i feel home at most (Heavy metal and related) thre is a huge scene of shirt bootleggers, that make very old school looking designs. These usually have quite a reduced colour spectrum (4 to 8 colours maybe). To make clear what i am talking about here is an example:

The originals to these shirts are these Cover artworks:

So i hope you get the idea !
My question is : How would i do this? From a guy i know who is a passionate avid photoshop user and professional graphic designer, i know how he does it with photoshop. He basically first uses threshold on the picture an then somehow colours a layer with a specific colour , then duplicates the picture , sets the threshold higher / lower, colours the next and so on, until those all together make a design like those above.
So i tried this with GIMP but i cannot seem to get past the part of colouring the first layer. i used the threshold feature, coloured all the black parts , but from then on it doesn't work. As far as i know Photoshop has somewhat of a function that you just put on a coloured layer over the picture, but i cannot find anything in GIMP. Maybe with a layer mask?
So : if anyone has any idea how i could achieve this it would be highly appreciated !
Thanks a lot in advance and please excuse if my English is a bit crooked, i am from Germany and it's not my mother tongue
Cheers
Hendrik
Edit: I played around a bit again and made a screenshot so it might be even more clear what i want to achieve. It gets a tiny bit into the direction i want but the problem is still the other colors aren't shining through

Definitely more than 4 or 8 colors. May be 4 to 8 hues, and a lot more tints. If you want to reduce the colors in an image, the best method is to make it color-indexed. For instance, one of your images, slightly blurred and color-indexed to 24 colors (no dithering). If you want to change colors in the result you just edit the colormap.

Thank you for your quick reply.
I am pretty sure though that this is not the way i intenended it to go. I would not like to reduce the colors per se, but color it myself step by step. So that i can even use different colors from the original ones if i wanted to.
For your description i am too much of a newcomer yet i am afraid, i have no idea how to do these things.... could you elaborate on that a bit more?
Currently watching a Davies Media Design tutorial on Layermasks and hope that can help me

While looking for a solution i found this thread and if i understand him correctly, being still a total beginner, i tend to think this is what i mean:
http://gimpchat.com/viewtopic.php?f=15&t=14447
I want to Use the threshold to a degree that almost everything is white, delete the black parts, then use the threshold on a duplicate layer with a bit more black, delete the black parts again and so on, maybe 4 to 6 times, and then colour those parts. That usually gives the whole picture a very vintage look.
But when i used the first threshold successfully somehow i cannot apply it to the duplicated layers, even if i hide the first one.

Because you have to make each layer "active" in turn to work on it (click on it in the Layers list). You may also want to hide the top layers temporarily (click their eye icon on the Layers list)
RE: Oldschool Shirt Designs / Threshold Question - CrystalLogic - 04-13-2021
Yeah i did both , i even deleted all other delayers on a test basis, but i didn't work nevertheless. Absolute mystery to me.
RE: Oldschool Shirt Designs / Threshold Question - Ofnuts - 04-13-2021
Oh, missed it. Your layer is in Grain merge mode. Depending on what is under it, changes may or may not be visible. Was it intended?
RE: Oldschool Shirt Designs / Threshold Question - CrystalLogic - 04-13-2021
Yeah was indeed intended haha, i tried basicylly every mode and played with the opacity of each layer to get something out that goes slightly into my intended direction. Without success so far
RE: Oldschool Shirt Designs / Threshold Question - Krikor - 04-13-2021
I'm not sure if I understand the content of the conversation discussed here, but ...
There is a script (Indexed Decomposed) that decomposes the image into a number of colors by layers.
Using this script you could decompose the image into 8 colors, each color in its layer.
Perhaps this would be an option.
RE: Oldschool Shirt Designs / Threshold Question - CrystalLogic - 04-14-2021
Yeah sorry in case it is a bit hard to understand, i can assure you it is equally hard to explain
That actually sounds pretty interesting! And then i can colour each layer the way i want individually?
I don't know how scripts work, havent dealed with them yet, is it easy to use these?
Thank you!
