Hi,

Based on this LEGO Color Palette video, I ended up looking to the various LEGO brick colors. 

Using Rebrickable Colors (csv), I was able to read it into Python, convert the hex values to RGB, and write an .ase file using Swatch. Import that into Affinity Publisher, and then export it back out as an .afpalette file, and you have the new EP Brick palette!

The new EP Brick palette has 224 colors, and has been added to the zip file. Each color has the correct name if you mouse over it.

Note that this is an RGB palette and not CMYK. Use caution if you plan to use this palette for print materials.
