Questiongraphics.h multi-threading problem Pin

I'm not sure if i should put this question in this forum or the Graphics forum, as the description in graphics forum only says DirectX,OpenGL or GDI.

So I was trying this graphics.h library that can crate simple graphic for console app. Everything works just fine until I multithreaded? it.

Ok, here is the code:
#include<graphics.h>
void drawrect(int l,int t,int r,int d,int col){
  if(col==0)setcolor(RED);
  else setcolor(BLUE);
  rectangle(l,t,r,d);
}
void drawpiece(int l,int t,int r,int d,int col){
  for(int i=1;i<5;i++)
    drawrect(i*16+l,t,i*16+r,d,col);
}
DWORD WINAPI Thread2(void* lparam){
  int px2=161,py2=17;
  for(int i=0;i<10;i++,py2+=16,delay(100))
    drawpiece(px2,py2,px2+16,py2+14,1);
}
int main()
{   
    initwindow(600,600,"TEST");   
    CreateThread(0,0,&Thread2,NULL,0,0);
    int px1=17,py1=17;
    for(int i=0;i<10;i++,py1+=16,delay(100))
      drawpiece(px1,py1,px1+14,py1+14,0);    
    getch();
    return EXIT_SUCCESS;
}

What i'm trying to do is to make two set of blockline. where first set is red and second set is blue.
this code makes the color mixed up.
So that's it. Any help would be greatly appreciated.
