The Brownie RGB LED Light from YC Onion, in black, is a small yet versatile light fixture suitable for on-camera use, as well as stashing it on the set and  in small spaces to get an extra bit of light where you need it. The fixture is fully adjustable throughout the RGB range, making it possible to match virtually any color. It is dimmable as well, from 100 to 10% brightness using a manual thumbwheel. RGB adjustment from 0 to 360° and dimming are both stepless for precise adjustments.

The fixture features a powerful magnet that enables mounting on most metal or magnetic surfaces, which is great for sticking it in a shot or hiding it from the camera without also having to hide any mounting gear. In addition to its magnetic properties, the Brownie has one 1/4"-20 threaded hole for articulating arms and light stands, and it comes with a 1/4"-20 to cold shoe mounting foot so you can attach the light to your camera's cold shoe. Three integrated cold shoe slots allow you to stack multiple units together to create a larger light source. The integrated 2000mAh battery will run the light for up to two hours.
