Firmin Baes occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Warm hues command this palette; Firmin Baes favours the reds, oranges, and yellows of firelight and earth. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The highest-chroma note - #62481A - appears at just 8.6%, deployed as a precision accent against the quieter ground. A value spread of 58 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. Palette 4 sits within the larger chromatic argument that Firmin Baes's complete body of work advances.
