PG18. Very Fast Drying. Semi-Opaque. Excellent Lightfastness. High Oil Content.
As one of the fastest driers in the range this hydrated variant of Chromium Hydroxide, introduced in the mid 19th century, is a valued support colour used for influencing greys in underpainting. The vivid blue undertones apparent in thin layers are soon eclipsed in thicker applications. Landscapists and some portraitists still prefer it to the more brutal power of the Phthalo Greens. When combined with reds an interesting range of blue-greys results.
