Answer:

Use a yellow (Red + Green) spotlight to make it look black.

Step-by-step explanation:

The blue fabric has pigments that can absorb the red and green light. This light is incident on the fabric, therefore, there is no light left to be reflected back, so, at plain sight, the dress will look black.
