but if we use default color by calling use_default_color, 
we will have an addition color number -1 for foreground and background
and this can have a combination  of init_pair(-1,0); to init_pair(-1,7);
and init_pair(0,-1) to init_pair(7,-1); which result in additional 16
pair which can be fully represented by the current max number of color
pair if we try to initialize all the available pair..i.e 8*8+16 = 80..
