XaoS is a fast, portable, real-time, and interactive fractal zoomer. It displays the Mandelbrot set (among other escape time fractals) and allows you zoom smoothly into the fractal. Various coloring modes are provided for both the points inside and outside the selected set. In addition, switching between Julia and Mandelbrot fractal types and on-the-fly plane switching is provided.
python-colormath is a Python module which abstracts common color math operations. (For example, converting from CIE L*a*b to XYZ, or from RGB to CMYK.) Other operations, such as calculating ANSI and ISO density from spectral data or taking the delta E of two colors, are also covered.
