Interpolate doesn't work with fill:fuschia and other color keywords

Steps to 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 workingbug.svg. Thank you.![bug.svg]
