The leaves of zucchini come in shades of yellow and of mottled green, both dark and light so unless they are actually wilting, the color you see is normal. If the leaves are dying it might be cultural or it may be a disease.

Common diseases include bacterial wilt, downy mildew, powdery mildew, and viruses. In the case of bacterial wilt, the leaves will begin to die. Cut the wilted stem and touch the tip of your knife to the sap. If it is milky and sticky, your plant is infected. Destroy infected plants immediately. Bacterial wilt, mildews and most viruses can be controlled or prevented with good cultural practices. Inspect plants often and control insect pests that can spread disease. Keep the garden clean and free of weeds and debris. Mildews can be reduced or prevented with proper watering and good air circulation.
