Transparent blue watercolor paints are either staining or non-staining. In addition, there are semi-transparent blue watercolors.
Transparent Non-Staining Blue Watercolor Paints
Cobalt Blue contains PB28-Cobalt Blue pigment. Jim Kosvanec Transparent Color Wheel lists Cobalt Blue as transparent non-staining. But, paint manufacturers label it as semi-transparent. It is commonly used as a pure color for glazing and for painting sky in landscapes. The pigment particles are large and grainy so it leaves a granulated effect on watercolor paper.
Transparent Staining Blue Watercolor Paints
Winsor Blue comes in two shades: Red Shade and Green Shade. Both paints contain PB15-Phthalo Blue pigments and are very strong staining transparent colors.
Indanthrene Blue contains PB60-Indanthrene Blue pigment. It is a deep transparent blue with a tinting strength that is less overpowering than Winsor Blue. Its best mixing complements are Hansa Yellow Deep and Raw Umber.
In addition to transparent non-staining blue, there are semi-transparent blue watercolors.
Semi-Transparent Non-Staining Blue Watercolor Paints
Antwerp Blue contains PB27-Antwerp Blue pigment. It is a slightly warm blue that is lighter than Prussian Blue. Lightfastness and permanence are good, but it has a tendency to fade when exposed to light. So, it is not considered ideal for permanent painting.
Prussian Blue contains PB27-Prussian Blue pigment. It is a semi-transparent watercolor with a deep cyan-blue hue and greenish undertone. It is similar to Phthalo Blue.
Cyanine Blue contains two pigments: PB15:1-Phthalo Blue & PB28-Cobalt Blue. The PB15:1 pigment produces more reddish tones making Cyanine Blue a warmer blue color.
