概要 In order to realize easy to use for paint-like compositing, we present two color compositing methods based on an RYB color model. The RYB color model proposed by Johannes Itten is widely used in art education, where red, yellow and blue are defined as subtractive primaries. Gossett and Chen [2004] proposed a conversion method from RGB color space to RYB color space based on tri-linear interpolation among three primaries. However, these conversion method is irreversible, i.e., conversion equations between RGB and RYB color models have not been proposed yet.
In this paper, we formulate mathematical and bi-directional conversion equations between RGB and RYB color spaces. We also propose simple color compositing methods to represent lower and highly scattering pigments compositing.
