Save, flatten and Color Balance
Make use of local colours
Using different Color layers, I fill in the base colours of the rest of the figure, such as her clothing, jewellery and the whites of her eyes. I also add an Overlay layer with a light orange to help lighten her shirt, because I want it to draw the viewer’s attention at first glance. I save her hair until last, so I can pick a shade that works best with the rest of the image.
Tweak the foreground colour
I’ll save a lot of the foreground painting for after the initial colouring process, but I want to choose the base colour before I flatten everything. While the blue underpainting will show through more in background shadows, the cool colour feels a little jarring in foreground shadows. I add more local green to make them feel closer and properly placed in the image.
Once I’m happy with the colours, I save a backup of the layered file. I take a deep breath and… Layer>Flatten Image. This is an essential part of my process while I try to get away from the super-smooth look of digital art. When I paint on one layer, I’m forced to approach it more like a traditional painting. I use the Color Balance tool to help harmonise the colours.
