If 'Interpolation' selected as 'Hyper-Palette' - then ALL COLORS in original picture will be packed to 256 colors. And In palette of image 'BLUE sea' - will be only BLUE colors (in count of 256 or less). No red, green and yellow colors in palette after opening image with only blue colors. Then if you want to open blue sea in 8bpp mode and print on it something red - then Hyper-Palette it is not your choice. But you can delete some colors on picture in this situation, and replace these free cells with red colors (See in detail - 'Command Menu' chapter, about 'Decrease CLR' and 'Decrease BPP')
