Titanium White — Titanium White is a permanent, heavy-bodied, versatile, opaque, pure white that is neutral in hue. It's ideal for applications where great opacity is required, and is considered the strongest tinting white.
Soft Titanium White — Soft Titanium White is a permanent soft-bodied, opaque, non-yellowing Titanium White that is ground in poppyseed and sunflower oils, rather than linseed oil. These oils do not yellow with age, as does pure linseed oil. Soft Titanium White is also recommended for fluid wet-in-wet techniques.
Zinc White — Zinc White is a permanent, heavy-bodied, semi-opaque, cool white. It's designed especially for brilliant clear tints with all oil colors, and is excellent for glazing.
Note — Use this color chart as an approximation of the real color. If exact color matching is necessary, use actual samples of the materials.
