Can anybody come up with a way to do tinted halation with the diffuse and sharpen module?

Achieving colored bloom or halation in Darktable?

Hi all, I have recently tried to come up with a way to achieve a colored bloom effect in Darktable (where the bloom (or halation) around the highlights has a different color than the lights themselves), but have failed so far (tried the usual suspects like the Bloom module or Lowpass). Any idea?
