Here are some examples of samples of gaussian process (seen as a function of the two dimensional space, time and color). In all cases the sampled GPs come from kernels following a Kronecker structure.

Brownian motion Kernels

Thresholded samples

The fact that there are only limited colors is that at some point I did a thresholding operation in each of RGB the channels, giving 8 colors.

Periodic Kernels

The moral here is that to obtain this periodic-like motion one can use a periodic Kernel
