Paint Inspired Color Mixing and Compositing for Visualization

Figure 1: Photographs of paint mixing. Left: A photograph of Red, Yellow and Blue paint mixing together. (The white spots are produced by light sources reflecting off wet paint.) Right: A photograph of overlapping Red, Yellow and Blue watercolor paint strokes. Color is often used to convey information, and color compositing is often required while visualizing multi-attribute information. This paper proposes an alternative method for color compositing. In or-der to present understandable color blending to the general public, several techniques are proposed. First, a paint-inspired RYB color space is used. In addition, noise patterns are employed to produce subregions of pure color within an overlapped region. We show examples to demonstrate the effectiveness of our technique for vi-sualization
