Add 'Brands' palette based on famous brand colours

[aebrer]

Add a new colour palette sourced from recognizable brand colours (e.g. Coca-Cola red, Tiffany blue, John Deere green, UPS brown).

Notes

• Source from publicly documented brand colour guides / hex values
• Names should be the brand name (or brand + descriptor if multiple colours per brand)
• Would pair well with Explore mode for a fun "name that brand colour" challenge
• Add to palette selector alongside Crayola, Pantone, XKCD, RAL
