This bright and cheerful illustration shows the BFG – a friendly giant. His has a big smile on his face and wears a colourful scarf. The background is filled with happy flowers and stars, hinting at the BFG's magical disposition. He stands in stark contrast to the other giants, who stand menacingly in the distance. They are large, intimidating, and filled with an evil aura. To emphasize the BFG’s goodness, I would colour the image in bright and happy shades of red, blue, and yellow. To illustrate the difference between the BFG and other giants, I would opt for darker and more muted tones like purple, black, and grey. I think this colour contrast would really accentuate the message of the illustration: even in a world filled with evil, there is still good.
