This drawing carries a mysterious air that’s perfect for a dark, high-contrast colour palette. The ghost could be shaded in greys, whites, or cool blue tones to highlight its translucent, ethereal feel. The night sky suits a deep black or a rich navy, while the moon can be painted in light greys with silvery details, or even pale yellows to light the scene gently. Dry, skeletal trees work well in dark browns, blacks, or even reddish tones to heighten the eerie mood. As for the graves and the ground, muted greys and subdued greens add weight and drama.
The interplay of light and shadow is key: you can leave a few areas uncoloured to create a subtle glow. And, to be honest, this is a great chance to play with gradients and highlights that intensify the fear the illustration suggests—think soft halos around the ghost or a faint sheen on the moon to pull the whole scene together.
