 Tomino's response in the novel version of "Gundam" is that the original design was to be a grayscale machine, made up of mostly white and light gray colouring.However, "Sunrise" disapproved of the colouring and insisted the unit to be painted in brighter colours to attract attention, like other super robot anime at that time.The "original" Gundam, the RX-78-2 design was to be the second unit in a line of eight prototype high-performance assault-type mobile suits.
