How to pick color palette and starter pieces for year-round capsule wardrobe?

[Tyler61]

I've decided to finally tackle my overflowing closet and transition to a minimalist capsule wardrobe, but I'm struggling with the practical first steps beyond just decluttering. My job requires a mix of business casual and at-home work, and I live in a climate with four distinct seasons, so I need versatility. For those who have successfully built a capsule wardrobe, how did you determine your core color palette and the exact number of pieces to start with, and what are the most durable, high-quality basics you invested in that actually withstand frequent wear and washing without falling apart? I want to buy less but better, but I'm overwhelmed by the options.
