These two rules often bother me because there are many ranked maps (more recent ones too) that do not follow them:
It may seem pretty/artistic to have your combo colours use the same theme as your map background but it's not easy to follow.
Here's an example: http://osu.ppy.sh/s/14978

(The main palette of the background is brown-ish and the combo colours are all shades of brown.)
A more recent example: http://osu.ppy.sh/b/188904
(Use of blue-ish colours on a heavy-blue background)
I know it's possible to disable the skin and use your own defined combo colours now but that requires you to playthrough the map once.and it shouldn't be necessary with this rule in place.
And here's an example of a map I feel is much easier to read due to the use of the colours: http://osu.ppy.sh/b/181827
(Using colours which very much contrasts with the background rather than blending)
Unfortunately however, it disobeys the other rule - no use of hitsounds at all.
Though the lack of hitsounds doesn't bother me as much as the combo colours as long as all notes follow the beat well.
- Combo colors must not blend in with the map's background/storyboard/video.
- You must use hitsounds.
