Why a palette tool?

People save 50 Pinterest pins and still pick the wrong orange

On Pinterest and Xiaohongshu, the recurring Halloween complaint is that saved decor looks gorgeous in one photo but clashes when you bring 12 different orange-and-purple items home. Discors and Instagram users also beg for "spooky but not childish" wallpapers. This generator locks five colors that are mathematically related, then tells you what the combination suits — so your porch, your phone background and your party invite stop fighting each other.
