**Final brushstroke-pigment correlation – Tree Oil vs. The Bedroom (1888)**
This image represents the final point in the Bedroom comparison set. It is linked directly to a critical scientific discovery: the brown pigment seen throughout the top section of the Tree Oil Painting — spanning the main trunk and branches into the leaf clusters — was sampled from overflow pigment between the painted canvas and its wooden frame. The pigment was analyzed under microscope as a pre-screening step before synchrotron spectroscopy.

What appeared brown to the human eye was revealed to be orange under scientific lighting. This comparison now supports a new hypothesis: not only are the brushstroke patterns consistent between the Tree Oil Painting and Van Gogh’s *Bedroom* (1888), but the true pigment color may also match.
