quadratura distributes its values across the middle register, creating harmony without high contrast. Built on cool foundations: the palette favours the blue-cyan-green arc. Chroma is moderate: colours carry enough saturation to be read as colour, but the palette stops well short of garish intensity. At 30.8%, #3F84D1 functions less as a colour accent and more as a complete atmospheric environment. The most saturated colour, #E6A333, is reserved to 5.7% of the surface, where it acts as a focal punctuation. The value range of 27 units sits in the comfortable middle: enough depth, enough light, neither extreme. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively.
