White synthetic brushes are the go-to tool in many artists' brush vases. Series 6100 has a soft flexibility that is perfect for low to medium viscosity paint.
Angular Brights/Shaders: Used for tight shading and curved strokes.
Brights: Length and width of brush is generally squared. Similar to flats, but shorter hairs make a stiffer brush.
Fans: Brush fibers are spread out making it useful for subtle blending and for textural effects.
Filberts: Create a softer edge than a flat or bright.
Flats: Longer hairs than a bright, this brush has more flex and a large color carrying capability.
Rounds: Smaller sizes are typically used for detail work and larger sizes tend to be used for washes and filling in color.
