Tobias Verhaecht occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. Tobias Verhaecht keeps warm and cool in parity, a balance that lends the work a perceptual shimmer. Saturation is deliberately withheld - the beauty here lies in the near-monochromatic gradations rather than colour difference. The most saturated colour, #403A23, is reserved to 10.1% of the surface, where it acts as a focal punctuation. The full value range is 74 units: broad enough to build convincing three-dimensional form. Palette 4 sits within the larger chromatic argument that Tobias Verhaecht's complete body of work advances.
