colors/hydrangea.vim different than python script output

[stelcodes]

Hi! Love this color scheme. I noticed while setting up fugitive.vim that the diffAdded and diffRemoved foreground and background colors are the same in colors/hydrangea.vim, making the text impossible to read. But when I cloned the repo and ran src/hydrangea.py, I got different output. It seems like colors/hydrangea.vim may be outdated?

Here's the result of running diff against colors/hydrangea.vim and the output I got from src/hydrangea.py
