How to use it
Suggested roles: #1F1233 as the background, #303B62 for cards and surfaces, #282047 as the primary brand color, #3E5779 as the accent, and #E8F3FE for text (a computed lighter shade of Slate, because no palette color is readable on that background). A reliable starting split is 60% background and surface, 30% primary and 10% accent.
Let one hue lead and let the others support it. Keep one color noticeably lighter or darker than the rest so the layout has a clear focal point.
