Refining the Sky

You can also brighten up (and increase the saturation of) the blue parts of the sky. I did this with cobalt blue and white. Finally lay in the more distant clouds that intersect the horizon.

Once the forms and details have been added you can add some more hue variations – in the lighter parts of the sky this will mean laying in both lighter pinks and lighter yellow.

Refining the Mountains

Begin by washing in a gradation of colour according to the dominate hue in each section of the painting. So in this case I went for gold at the top for the cloud, transitioning into pink for the mountains and then blue and grey lower down the image (in the foreground). You can keep the layers quite transparent by using a lot of water to create very washy passes.

Once these gradients are established you can start to build more specific hue and tonal variations throughout the image. You can use the still visible pencil sketch to help you figure out what is a cloud, sky or mountain etc.

Keep adding these variations down the entire painting – ideally getting the darker notes establish for the trees and shrubs in shadow. The colours don’t need to be perfectly accurate – we’re just going for a bright and engaging image, so follow what feels best to you!
