In this coloring page there is a joyful boy with yellow hair enjoying a skateboard ride down the road. He is wearing a bright blue t-shirt and bright red shorts that contrast nicely against the warm yellow of his hair. His skateboard is a deep black with yellow wheels. The yellow and red of his clothing and the yellow of his hair provide a bit of sunshine brightness that gives the page an upbeat, cheerful feeling. I would suggest coloring the boy in similar shades of yellow and blue and using a bright red for the shorts. For his hair, I would use orange for the highlights and yellow for the rest. Using a bright yellow for the wheels on the skateboard will make them stand out. To top it all off, a nice pale blue for the sky would give a cloudless, happy feeling to the page.
