Why am I only seeing one set of colors

For this type of overloaded printing, Jupyterlab only prints the last thing returned in a cell, try separating it out into four cells, or returning a vector of images from a single cell:

[
    reshape([RGB(rand(),rand(),rand()) for _ in 1:12], 4,3),
    reshape([RGB(rand(),rand(),rand()) for _ in 1:12], 4,3),
    reshape([RGB(rand(),rand(),rand()) for _ in 1:12], 4,3),
    reshape([RGB(rand(),rand(),rand()) for _ in 1:12], 4,3)
]
