marina is high-key - luminous, open, and weighted toward light. Built on cool foundations: the palette favours the blue-cyan-green arc. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. 26.2% of the palette belongs to #A2AFBC, a concentration that makes it the unmistakable visual centre. Only 9.3% is devoted to #788AAB, yet that small allocation delivers the palette's entire chromatic tension. Spanning 54 units on the value axis, the palette achieves the balance between tonal flatness and fragmentation. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source.
