Where are colourful app icons in the Adwaita icons theme?

Hello,

I have been searching for every folder and subfolder in the Adwaita icons theme folder. I found only symbolic icons and monochromatic icons. On 512x512, only colourful apps icons do not exist.

My goal is to make third-party icon theme very minimal, removing unnecessary icons, because it will inherit from the original Adwaita. The guy made a Shell Script code for me, like:

#! /bin/bash

adwaita_original="/usr/share/icons/Adwaita"
adwaita_plus="$HOME/GitHub/adwaita-plus-beta/Adwaita++-Minimal"

# map the Adwaita sizes to Adwaita++ sizes
declare -A size_mapping=([16x16]=16 [24x24]=24 [32x32]=32 [48x48]=48 [scalable]=symbolic)
declare -a directories=(actions apps devices emblems mimetypes places status)

for size in "${!size_mapping[@]}"
do
    for dir in "${directories[@]}"
    do
        for i in "$adwaita_original/$size/$dir/"*.{png,svg}
        do
            # Take just the filename ${i##*/} and build the new path
            plus_file=$adwaita_plus/$dir/${size_mapping["$size"]}/${i##*/}
            if [[ $plus_file = *.png ]]
            then
                # replce the extension with svg
                plus_file=${plus_file%.png}.svg
            fi
            [[ -f "$plus_file" ]] && rm -i -rf "$plus_file"
        done
    done
done

On the third-party icons theme, the colourful apps icons on the folder apps/scalable without -symbolic suffix. On original Adwaita, on 512x512 without -symbolic suffix, but the apps folder does not exist. On other folders, apps folders are only monochromatic and symbolic.
