When comparing two groups or dealing with paired samples, having paired color scheme is helpful! Here are two legends from a Rescript graph where I want to use a paired palette! <img width="188" height="136" alt="Image" src="https://github.com/user-attachments/assets/7d73ec65-a2fd-4bae-a039-50665fa4bcdf" /> <img width="175" height="116" alt="Image" src="https://github.com/user-attachments/assets/7b61cc8b-81fa-4784-bd7a-941f99c5ed2b" /> Custom color palettes would also address this problem!
