11/30/2023 0 Comments Cobalt blue color chart![]() I almost always mix either a red or a yellow into my "blue" sky and this becomes compounded by the presence of a cloud cover. I never use just a pure blue (plus white) for a sky, because the colors and temperature are so dependent on time of day and surrounding colors. The important question when painting skies is what colors will you be mixing with the blues and how will you go about doing that? That is where the "Art" comes in. And, of course, the Ultramarine is essentially transparent, while the Cobalt is opaque. If you do this side by side, you can compare the two chromas. They are slightly different in color temperatures, which can be best understood by mixing them out with a white. "I use Ultramarine and Cobalt as my primary blues. Be sure to try your own color charts.)Ī Summer Cast 24 x 30" Oil George Van HookĪutumn Valley 24 x 30" Oil George Van HookĪbove: Low pressure moving in from the south (left side) high pressure still to the north.

Just trust your instincts and keep trying until it WORKS!" I've had many paintings that I have repainted the sky several times changing the blue. It all depends on what other colors are in your painting. Some paintings call for a warmer Cerulean sky some for a cooler Cobalt one or some Ultramarine or combinations of all there or even other blues. "There is no real formula to choosing which blue to use in your sky. Lyrical Light 24 x 30" Oil Howard Friedland On a clear sunny day, the sky could be a light Cobalt Blue at the top of your painting and as it descends down to the horizon you might see it warm up to a light Viridian Green hue and at the point where you lost sight of the sky, it might even have a red-violet tone like a bit of Alizarin Crimson blush." Now watch the sky change temperature as you move your finger. Here is a neat way to observe the color shift: using your finger, point at the sky moving it slowly from side to side or zenith to horizon. Also, depending on the time of day, it might graduate warmer to cooler from side to side. As the sky descends slowly toward the horizon, it gets lighter and gradually warmer. How does the color transition from warmer to cooler? Notice how the sky above you, at the zenith, is a darker and purer blue. The other thing I look for is gradation in the sky. Therefore, whichever blue I use, I'll want it to harmonize with the rest of the painting. When I think about painting skies, I remember that whichever blue I use, on a clear sunny day it will influence the horizontal planes and the ground and much of the shadow color. Even Viridian Green can look bluish in certain color combinations. The key is to remember that color is relative and will look a certain way when placed next to other colors. I think of Cobalt as the purest and coolest of the blues since Ultramarine has a blue-violet cast and Cerulean has a comparatively warmer (greener) feeling. ![]() That said, I have Cobalt Blue, Ultramarine and Cerulean Blue as staples on my palette. "Skies can be any color and not just blue.

For the landscape painter, learning the characteristics of available blue pigments is essential. Changing atmospheric conditions, time of day, time of year-all can create nuanced, or sometimes dramatic, variations in the color of blue of the sky.
