I have to assume that there are other filters that are tested against this

I think the same way too. :)

Please someone correct [me/us] if [I'm/we are] wrong. I definitely have no
idea how unit tests written :) This patch written on hackathon to solve a
bug as Siqi said.

Tests are written according to the reversed start and end colors(Old code
which we changed). After our change at hackathon expected value is wrong
because test is written for the old code. So reversing the expected and
given HEX values to test should cause reversed values. So maybe it means
code is working as expected and the problem is test is written according to
reversed values(old code) ?


(Good luck to understand the paragraph above :))
