Hello, I am very happy you liked the demo <3
As for the hair colors, unfortunately we won't add more even in the full game. Our artist is very perfectionist so it's not just color swap, they redraw everything each time so the shadows, contrast with the clothes and skin etc. are always perfect. Since the MC will have several hairstyle, several clothes, several color skin, it makes way too much variation to account for, so we decided to let them as it is I hope you understand!
Thank you for your support,
Ayael
