So I started implementing colors in the timeline. I agree that we should ideally use variations of the theme's original colors, in our case mostly breeze dark: https://community.kde.org/KDE_Visual_Design_Group/HIG/BreezeDark

I am not sure we want a different color for each clip type. This would make the timeline quite messy in my opinion and distract the user. But I am open if you think it's better.

ok, I did "git clone", "git checkout", changed the line in colorwheel.cpp, "git add", "git commit", but "git push origin refactoring_timeline" throws an error "
fatal: remote error: service not enabled: /kdenlive.git"

I just tried to git the actual sourcecode from the refactoring_timeline branch, but get a build error:
kdenlive/src/bin/bin.cpp:694: error: ‘renameFile’ is not a member of ‘KStandardAction’

m_renameAction = KStandardAction::renameFile(this, SLOT(slotRenameItem()), this);

Just as an addon-info to this.
At the moment, resetting the color wheel does only that - the line values are not effected.
The other way around it's not like this: resetting the line will also reset the color wheel.
For what I saw on all color correction hardware, there are 2 seperate buttons to reset the wheel and the overall values.
