This coloring page features a classic CD player with a bold blue light. The crisp black and white CD in the player looks striking against the shiny exterior. The yellow "Trolls - DJ Sounds" sticker adds the perfect splash of color to the design. To enhance the image, consider using a variety of shades for everything from the light to the CD, sticker and player exterior. Perhaps opt for a bright blue for the light and a lighter yellow for the sticker. Then use a mix of blacks and greys for the CD player, playing around with shading and texture. Finally, a bold black could be used for the CD, creating a strong contrast with the light blues and yellows. Experiment and have fun!
