Remove all the handwritten notes and swatch codes, the sideways caption and 'brow tust', '7751' and '203' at the left edge, 'koi fish mar' at the top, 'hool water fort' and 'color swatch' at the right, leaving plain paper; keep the colour swatch squares, the coloured-pencil koi over dark blue water and everything else exactly as it is.
