I'm surprised such "crawling" glazes are on the table, there's probably a lot of nightmares about what the final product would look like given what the 3D model looks like.
My thought process for selecting them would be to start with the options that are the most distinct, so I'd drop the pink that's counterclockwise from the red, and then the green between the blue. Then, the yellow looks awesome, but in practice it'll be too close to white. It'd be awesome if I could just have a choice of those four and white, but if I had to narrow it down further, I'd keep red and blue out of preference.
Is your kiln electric or gas based? If it was gas-based, I'd be concerned that a lot of the red glazes I've worked with will green if the kiln isn't properly oxidizing, which isn't always easy to guarantee.
I am not a big fan of brightly coloured ceramics especially when they are glossy. They always look a bit like child-like and I guess the necessary thickness of the printed ceramic material doesnt help that aesthetic.
So for me, I would prefer just black and white, and a matte/satin and gloss option for both. but this is me being a purist I suppose
