Alternative Lighting Colored LEDs

In photography you could use alternative lighting colored LEDs to express a deeper meaning to the photo. For example on St. Pattys Day you could use a green, white, and yellow light to express the day, or if you want a photo with a sad emotion bonded with it, you could use a dark blue light. The hue color of a photo can convey many different things, and since there are so many different colors with different things connected to them, the possibles are endless. Some downsides of this type of lighting is outside during the day forms of this lighting can be hard, and these types of pictures usually are dark.
