What is added to the flash head when mixing fluorescent light with flash to correct color?

1. Red gel

2. Blue gel

3. Green gel

4. Yellow gel

The correct answer is: Green gel

When mixing fluorescent light with flash, a green gel is added to the flash head to correct color. Fluorescent lighting often has a greenish tint due to its spectral output, which can result in unwanted color casts in photographs. By placing a green gel over the flash, you can effectively balance the color of the light emitted from the flash with that of the fluorescent source. This adjustment aids in achieving a more neutral color balance in the final image, ensuring that colors appear true to life. The other options, while they might influence color in various contexts, do not specifically address the green cast typically present in fluorescent lighting. Therefore, they are not the appropriate correction for achieving accurate color in this situation.
