I would color the LOL doll in bright, vibrant colors. I would start with the blue of the head, using a light and dark blue combination to create a sense of depth and reflection. I would then fill in the black plastic ring, legs, arms, top, skirt and base with different shades of grey, while bringing out the definition of the points and ruffles with a darker shade of grey. The eyes and mouth would be black, and the buttons and bow would be white. For a finishing touch, I would add an extra pop of color to the white bow with shades of yellow and pink.
