Try increasing the "creativity" slider in the options. Setting it to a higher value will increase diversity at the cost of accuracy. (This controls the sampling temperature like in language models) When I use the tool myself, I usually start with the transformer model to lock the first few colors, then switch to the diffusion model if I see a repeat. When all colors are locked except one or two, the "random" mode starts working if you still need more variations.
