I have slowly been adding to my Daniel Smith watercolors collection. This is a Meeden tin I purchased from Amazon. I removed the tray that held the pans in (it came with half pans but they sell them empty - this one just happened to be cheaper) I attached small adhesive backed magnets to the bottom of the full pans and placed them in the tin.
I bought a couple sets, so I ended up with a couple similar / same colors, but the price was better buying them in the set than individually at the time. Here is the list of colors I currently have, it zig zags starting from top left. They are arranged in the order Daniel Smith lists them in their chart:
Hansa Yellow Light
Hansa Yellow Deep
Permanent Red Deep
Phthalo Blue (GS)
Quinacridone Deep Gold
Transparent Brown Oxide
Burnt Sienna Light
Everything looks so messy because I started out by putting these paints in a tray palette and in half pans but decided later I didn't like those and wanted full size pans. If you take a look at one of my older posts I made a demo video of my process for transferring these paints. Daniel Smith paints are too expensive to just not salvage them!
There are a few colors I'm realizing I never use. Those were generally some of the colors I got initially. I bought these two sets on Amazon: The Alvaro Castagnet Set and the Essential Mixing Set. They were a steal at the time and I ended up getting them for around $4-5 / tube by buying them this way. Whether I saved much money is up for debate considering now I have a few colors I don't really use and I ended up with 2 nearly identical ultramarine blues.
I'm curious what your go to colors are? Which do you absolutely have to have in your palette? I have room for a few more pans in this box and I could swap out a couple others I don't really use so I'm up for suggestions!
