Merging colors... How do it with Gimp?

[cli345]

I had made it only for 3 layers and I forgot to restore the input layers.

Here is a fix:

Code:

split_opacity

rgb2hsv[0--1:2]
repeat $! l[$<]
    split. c
done done
fill[0--1:4] if(i<60,i*2,if(i<120,i+60,if(i<240,i/2+120,i)))

100%,100%,1,1
fill. x=0;y=0;for(n=0,n<l,x=x+i#(n+3)/255*cos(pi*i#n/180);y=y+sin(pi*i#n/180);n=n+4);(90-180*atan2(x,y)/pi)%360

fill[0--1:4] if(i<120,i/2,if(i<180,i-60,if(i<240,i*2-240,i)))

100%,100%,1,1
fill. m=0;for(n=1,n<l,m=max(m,i#n);n=n+4);m

100%,100%,1,1
fill. m=0;for(n=2,n<l,m=max(m,i#n);n=n+4);m

100%,100%,1,1
fill. m=0;for(n=3,n<l,m=max(m,i#n);n=n+4);m

repeat $!
    if $<%4==0
        second={$<+1}
        third={$<+2}
        local[$<,$second,$third]
            a c
        done
    fi
done

hsv2rgb[0--1:2]

repeat $!
    if $<%2==0
        second={$<+1}
        local[$<,$second]
            a c
        done
    fi
done
