Above my initial black tonal underpainting of the oversized gourd, I will paint a color layer, using yellow ochre, cobalt blue, white and black. I’ll mix a string of progressively lighter values of both colors. Then I’ll mix a middle row of the two combined 50-50 %. Afterwards, I’ll mix a range of all values with a small amount of black to further neutralize.
I’ll paint the background a cool light value from the cobalt/yellow-ochre side, and the foreground with a light value from the yellow-ochre side.
One of the darker cool greenish values from the middle string is applied for the dark values on the gourd. Lighter warm yellow-ochre values for the lightest lights on the gourd.
Next, find the middle values and place strategically.
A gentle smoothing and adjusting. Now let this dry until next time, when a final pass of color will be applied.
