Project Description:
This project will explores how video projections use additive color space to create a full color image. Using live video, the viewer's image is captured, projected in full color, and then manipulated to separate out the primary additive colors (red, green, blue) which are then projected onto each corner of the space. Where the primary additive colors mix in the centers the viewer sees the secondary additive colors (magenta, yellow, cyan). The viewer's shadows will also block and interact with this color mixing process. While the viewer is interacting with the exhibit, still images will be captured and stored on their visitor badge; these can later be printed out as the full color image, or as the 4-color separations which form subtractive color space.

The structure: Three rainbows will overlap at the edges to form the triangular scaffolding structure of the exhibit. Falling from the rainbows will be panels of semi-opaque fabric (about 75% opaque), three panels of fabric per side of the triangular structure. Within the fabric triangle will be a video camera capturing live feed of the project. The camera will be housed within a disco ball.

The visuals: The live video feed from the interior camera will be projected in two different formats. The video feed will be projected "normally" onto the floor in the center of the triangle, with the exception that it will be rotated 30 degrees, so someone standing in the triangle will not be standing in their own projection, but will be standing in the corner adjacent to it. The video feed will also be projected onto the fabric panels, but this display will only reveal the red, green or blue information from the video. The reds in the image will be projected from one of the corners of the rainbow scaffolding onto one of the fabric corners of the triangle through two projectors (the image must be mirrored for each side of the corner); the blue and green will be projected from one of each of the other corners. Where the colors meet / overlap in the centers of the fabric panel secondary colors will be formed.

The secondary visuals: Secondary visuals will be formed through the shadows of viewers moving in front of the projected video feeds. As the projected feeds will be coming from different directions, the shadows will be multiple, and will never completely obscure the video. Furthermore, as an example of subtractive color blending, viewers will have the option to have stills from the video feed stored in their visitors badges. These stills will be available as the full color composite and the 4 color separations.

Other visuals: When no one is in the exhibit, light activity will occur through the natural spot-light effects of the disco ball being captured and re-projected onto the fabric panels.
