Frans Arnold Breuhaus de Groot sits in the centre of the value range, lending the palette a sense of even, sustained light. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. All colours lean toward grey, building depth through value rather than colour punch. A single dominant - #14110D at 32.4% - sets the character of the whole composition. The saturated accent, #CADEE9, registers at 4.0% - sparse enough to feel like a deliberate surprise. 75 units of value range underpin the palette's structural clarity: the eye always knows where light falls. This is palette 5 of Frans Arnold Breuhaus de Groot's sequence - a single chapter in a chromatic story told across many works.
