White oil paint comes in various types, they all have different uses depending on what your trying to achieve. In my experience they are all all slow to dry but certain mediums like Liquin can be added to speed this up.
The most popular of all the whites, bright and the most opaque of all the whites, great for blocking in. A more chalky texture.
Is a warm white, opaque, quite stiff and drys slightly quicker. Low tinting qualities makes it useful for mixing with other colours. Popular because of its warm tone, quicker drying time and creamy, workable consistency. My favourite for portraits as it creates supple skin tones.
The most transparent white, cool white colour, ideal for tints and glazes. A good option for lightening colours more subtly without losing the transparency.
Good for any underpainting and quite opaque.
Good for textures, warmer in colour and semi-transparent.
This is a mixture of Titanium white and Zinc White, which means it more transparent than regular Titanium White. Good for glazes and tints.
A semi-opaque white, which gives a pearl effect.
