In the coloring page, there is a man with a determined expression on his face standing in a dimly lit room. He is wearing a bright green shirt and blue jeans, and a scarlet red scarf that is draped around his neck. In his right hand he is holding a black device with a blue light emanating from its center. To really bring this page to life, try using a mix of warm and cool colors. Start with the man himself; make his shirt a bright apple green, and his blue jeans a navy blue that almost looks black. For the red scarf around his neck, you could go with a deep scarlet or even a burnt orange to contrast against the greens and blues. For the black device, you could use a dark charcoal gray with a bright blue shining out from the center. As for the background, you could choose a light teal to contrast the more vibrant colors of the man and device. Have fun with it and try experimenting with different color combinations!
