Different Blues in Oil Colors
|Types of Pigments in Oil|
Most artists will use just a dozen or so oil paints (as do I) which includes a warm and cool version of the primary colors (red, yellow and blue) as well as earth colors, a few extras and white. I find the following oil pigments will mix just about any color needed for painting: Titanium white, French ultramarine, Pthalo blue, permanent rose, cadmium red, lemon yellow, cadmium yellow (pale), burnt sienna and burnt umber. The following are also useful extras: cerulean blue, viridian and alizarin crimson (an old favorite).
Using Oil Paints for the First Time
A good way of learning about the nature of each pigment is to apply each alone on a primed piece of card. The video clip informs on how each oil color differs in translucency and color temperature (how warm or cool it appears). Nothing quite equals trying out each color for yourself as opposed to reading about them, but basically, each color will have its own intensity, opacity, temperature and translucency. Find a YouTube clip on how I applied each oil pigment neat onto white card.
Translucent Blues and Reds
|Color Temperature of Blue and Red|
This can be seen with viridian, which is also a transparent color. I applied it neat, and then with a little titanium white.
Opaque Pigments in Oil Colors
|Color Temperature of Yellow Brown|
Colour Temperature of Pigments
How warm or cool does the color appear? This is known as colour temperature. A warm color will be bias towards red, a cool colour will be bias towards blue. French ultramarine has a violet cast, meaning it has a warm colour temperature. Cerulean blue and Pthalo blue appears cooler. Cerulean has a slightly greenish tinge. Again, cadmium red has an orange-glow, giving it a warm cast. Permanent rose and alizarin crimson are cooler reds, having a violet cast. Similarly, burnt sienna is a warm, toasty brown; burnt umber is cooler.
Guide to Oil Pigments Transparency and Colour Temperature
French Ultramarine: a warm, violet blue, tends to be translucent
Pthalo blue: a cool, deep blue, tends to be translucent
Cerulean blue: a cool, greenish blue, tends to be opaque
Viridian green: A sharp green, tends to be translucent
Permanent rose: a cool, violet red, tends to be translucent
Cadmium red: (deep to pale can be found) but tends to be orange-red, rather opaque
Alizarin crimson: a deep, violet brownish red, tends to be translucent
Lemon yellow: a pale, acidic yellow tends to be translucent
Cadmium yellow: (deep to pale can be found) but tends to be warm, orangey, rather opaque
Burnt sienna: a warm toasty brown, tends to be translucent
Burnt umber: a cool, coffee brown, tends to be opaque
Titanium white: a brilliant, opaque white. Will add opacity to any pigment it is mixed with.
