Keyframe Colours
The colours used for keyframes might be counter-intuitive for newcomers. Typically the paradigm is red:bad ; orange:warning; green:ok
In Blender, we have mushy orange for a Keyframe not set and a different mushy yellow for an active keyframe.
Different colours?

Keyframes are orange for visual consistency with other areas.
In any case, it's already a theme option:
