The size of each zone should reflect your workflow. A UI designer may give more space to the primary work zone, while an illustrator may need a larger creative area for a drawing tablet. Photographers and video editors may need a more accessible support zone for storage devices, memory cards, and audio equipment.
The goal is not to fill the desk with creative accessories, but to give every tool a clear place so that moving between tasks requires less reaching, reconnecting, and rearranging. Task lighting should be planned to support both the primary and creative work zones, rather than treated as decoration around the setup.
Many iMac setups already use ambient or decorative lighting to create atmosphere, but these lights often illuminate the wall or surrounding space rather than the areas where work actually happens. A productive setup also needs functional light for the keyboard, drawing area, and physical references—without creating screen reflections or taking up valuable desk space.
