The sky is awash with an array of vibrant colours, as fireworks light up the night in celebration of the New Year. The city skyline is silhouetted in the distance, with the brilliant hues from the display reflecting off the tall buildings and framing the night sky. To create an eye-catching piece, use a combination of cool tones to colour the sky and buildings, while bright oranges, purples and reds help to add depth to the fireworks. Add yellow and white highlights to the buildings to bring out their details, and give the night's sky extra vibrancy with metallic silver paints or glitter. Finally, use darker shades of blue and grey to add to the mood of the scene, as well as detail to the silhouette of the skyline.
