Brown Iron Oxide
Arylide Yellow
Ultramarine Blue
There may have been a formulation change here and sources differ on what exactly it was. Previously it appears that it may have been formulated as PBr7 PY74 PB15:1 (PB15:1 Phthalo Blue PY74 Hansa Yellow PBr7 Burnt Sienna), whereas the Gamblin brochure downloaded in 2023 read PBr7 PY75 PB29 (Ultramarine Blue). So the PY74 seems to have been replaced by PY75 and the Phthalo perhaps swapped for Ultramarine. Gamblin categorizes the color temperature as warm.
