RGB-based parametric color mixing system for digital painting

Abstract:

Techniques are disclosed for parametric color mixing in a digital painting application. A methodology implementing the techniques according to an embodiment includes generating a Bezier curve extending from a first point to a second point in a 3-Dimensional space. The first and second points are specified by coordinates based on red-green-blue (RGB) values of first and second mixing colors, respectively. The Bezier curve is defined by a selected curvature parameter which can be related to the paint medium, such as oil colors, water colors, pastels, etc., and which further specifies additive or subtractive mixing. The method also includes locating a point on the Bezier curve, the point determined by a selected mixing ratio parameter specifying a ratio of the first mixing color to the second mixing color. The method further includes generating a color mix based on RGB values specified by coordinates of the located point on the Bezier curve.
