“The most opaque white. Very strong covering power.” “Williamsburg safflower oil-based colors are designated with a light blue, translucent “SF” behind the color name on the label and a “SF” before the name on the color chart. These colors also have a black ring around the label stating that they are a safflower oil-based color. Colors ground in safflower oil are known to yellow less over the long-term than linseed oil-based colors. SF Titanium White is noticeably brighter and slightly cooler than our linseed oil Titanium when squeezed from the tube. While similar in feel and tinting strength to its linseed counterpart, it should be noted that safflower oil is a less durable binder than linseed oil. This means it is best used thinly and or in the upper layers of a painting where its bright white color will be most appreciated. One of the main reasons to use this color is to make white passages or high key mixtures in the upper layers where a bright white will be most noticeable and where less yellowing is desired.”-Just Paint 2020 -Williamsburg
