Additional file 4: Fig. S4. Raman spectra of a sample S6 from house post 16/568, i.e. “intact” area of black paint from the bear’s eyebrow, and b sample S4 from house post 16/568, i.e. “intact” area of red paint from a woodpecker at the top of the pole. In spectrum a, bands at ≈ 1335 and ≈ 1575 cm− 1 are assigned to a carbon-based black. In spectrum b, bands at 252, 284, and 343 cm− 1 are attributed to vermilion.
