Ok so here is what I have done for myself as each colour has a third variable being the L (lightness). So to display this I have the grid arranged by colour and hue and then grouped by their L value.
In reality this should be a “colour cuboid” and each of these groups stacked on top of one another. Also I realise that I should of ordered each group in the opposite order, but it serves it’s purpose.
Disclaimer: This is a sheet ripped off another sheet and simply rearranged by me for my purposes. The clever stuff is not my work and I take no credit for it whatsoever.
From the shop owner perspective number is easier to keep it organized and to always have the right amount of room from a shopper perspective I prefer color. I’m still holding out hope that they will put color number tints In an update
