How to use it
Suggested roles: #C3CC28 as the background, #728319 for cards and surfaces, #A8B617 as the primary brand color, #989A20 as the accent, and #1D1C04 for text (a computed darker shade of Olive, because no palette color is readable on that background). A reliable starting split is 60% background and surface, 30% primary and 10% accent.
Use the lightest color for large areas, the mid tones for structure, and the darkest for text. Add contrast through lightness, since hue will not do it for you.
