Nandalal Bose works in the upper reaches of the value scale, creating an atmosphere of brightness and expansiveness. Blues and teal-greys govern the palette, lending it an aquatic or atmospheric quality. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. Only 8.4% is devoted to #3F5190, yet that small allocation delivers the palette's entire chromatic tension. 66 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively. This is the light Nandalal Bose preferred, made measurable.
