In RGB space #0D3D2F is a distant relative of CSS black — about 78 units away from #000000. Designers reach for spring green hues at this saturation when the brief calls for a conversational, mid-energy register, and at this lightness when they want weight, depth, and grounded contrast. On screen the cool cast tends to pair best with warm neutrals in the 25°-45° range to add life.
