This person is hard at work in their laboratory, surrounded by beakers and test tubes. Some of the beakers have smoke rising up from them, indicating some sort of experiment. The person is taking extra precautions and has on protective gloves, as well as a snug mask, to protect them from any potential dangers. Their intense gaze is focused on a microscope, probably examining the results from their experiments.
To color this scene, start by layering in some muted colors for the laboratory walls and floors. Use greys and blues to add a sense of science and technology to the scene, and introduce small hints of light greens and yellows that suggest medical safety warnings. Particularly around the person’s gloves and anywhere near the beakers, we can emphasize those light colors to illustrate the extra precautions the person is taking. Make use of shadows by adding darker colors at the edges of the beakers and other items to add depth. Finally, paint the person in a brighter color, like green or yellow, to make them stand out and draw attention to their diligent work.
