Palette Description:
The “Extended Tonal Harmony” palette maintains the core colors from the original while introducing new shades like powder blue for a softer touch and peach puff for a warm, inviting accent. Steel blue adds a deeper tone to the palette, while rosy brown brings in a subtle, warm contrast. This expanded palette offers even more versatility and depth for your design needs.
