Palette Description

This palette consists of muted and desaturated colors suitable for a map, featuring a variety of tones with distinct variations. The first color is a muted green with four tonal variations, followed by a yellow-green range that transitions from green to softer shades. The palette also includes unique colors and stronger tones for hachures. Each color has been carefully selected to maintain a cohesive look while providing enough distinction for functional mapping purposes.

Do you need any further adjustments or additional colors, or is there something else you would like to explore?
