Here is a picture I am working on. It is acrylic on Crescent multi media board. The sky is chalky looking. Any suggestions on how to remedy this? Your help is deeply appreciated.

Hi Dee,

It is hard to tell from the image the actual reason you see chalkiness in the painting. It looks like you used cerulean blue as an all-over solid area of color. (?)

Look at the sky compared to the adjacent rocks. Sometimes we tend to make a sky hole looking through trees or rocks lighter than they really are because we know they are light. Double check first to see if you have the correct value. Then check the actual colors in the sky.

Since I can't see the photo or scene you painted from I'll just give a couple of tips. The sky is generally more saturated in color and lower in value at the top, then gradually gets lighter and a tad warmer as it reaches the horizon (where the violet mountains you have are.)

See if you may have a hint of red or orange or even yellow at the horizon in the actual scene. Then add what you need to warm it up (ultramarine, a red or a yellow.) Also, use white carefully. To avoid that chalk-like appearance, use other lighter colors before adding white.

And lastly, work from dark to light. If you attempted to put in light sky colors first then added in the darker colors/values over top, you can get a chalky look.

Hope these tips give you some ideas to try. Your painting looks very nice from here!

Hello Dee,

I cannot really see the chalky bits in this picture and I don't know the multimedia board you mention, but I'll take it that it has a ground of acrylic gesso.
Here is some guesswork though: might that you used too much (thick) titanium white; in that case try zinc white.
In general if you use transparent colours and glazing or glossy medium you shouldn't get chalky effects.
You could try redo your sky with opaque colours like yellow ochre, light red and white and then glaze it with ultramarine or phtalo blue.
