The value structure of Jan Siberechts is mid-key: quiet, controlled, and cohesive. Jan Siberechts keeps warm and cool in parity, a balance that lends the work a perceptual shimmer. Every colour is desaturated; the palette proceeds through near-neutrals and gently-coloured greys. The most saturated colour, #E03B27, is reserved to 1.6% of the surface, where it acts as a focal punctuation. From deepest dark to palest light, the palette traverses 60 units of the value scale - a span that creates natural depth. Taken together, these qualities constitute Jan Siberechts's chromatic voice - distinctive enough to be read across an entire body of work.
