<!-- See our full bug reporting guidelines at https://inkscape.org/contribute/report-bugs/ Writing a good bug report will ensure we'll be able to help efficiently. 🙂 --> #### Steps to reproduce: <!-- Describe what you did (step-by-step) so we can reproduce: --> I draw 2 squares with same width and height (primitive shapes) one filled in lime the second one in fuschia, I converted them into paths. I distributed them in order to have a space for 2 intermediate squares. I selected both paths, went to menu extensions/generate from path/interpolate. In the window "interpolate" I checked "interpolate style", chose "2 steps interpolation" and method1/ or method2 (tested both) and click apply. #### What happened? On group of 4 squares (shapes) were produced in lime. Dimensions ok. #### What should have happened? It should have outputed 2 square shapes with intermediary colors. I made another try, on square in yellow, the last one in red, it should have produced 2 orange squares (2 tones)! Morover darken color does not work too. Please let us know how to make python scripts working.
