Color – warna merupakan hal yang cukup sulit dalam computer vision, ada begitu banyak kombinasi warna. Secara umum ada 3 warna basic yaitu RGB yang bila dikombinasikan ada sebanyak 2^8 alias 256 jenis warna. Nah bagaimana Segmentasi warna berdasarkan Color Palette untuk gambar jeruk dibawah ini??
Berdasarkan percobaan, gambar jeruk diatas bila diplotkan kedalam RGB menghasilkan sebagai berikut
Kalau kalian merujuk pada https://www.rapidtables.com/web/color/RGB_Color.html disitu disediakan informasi nama warna serta kode hex dan RBG nya. Ada 2 tabel yang basic dan yang full.

hasilnya lebih bagus lagi yaitu dominan orange dan green
