What do green/brown(orange?)/yellow attribute highlights mean? Shown here, a green (location (x,y,z)), brown (rotation (x,y,z)) and yellow (scale (x,y,z)) colored attribute highlight. What do these mean? (And where are they documented?)
These colors all have to do with Keyframes.
Yellow: Keyframe has been set on current frame
Green: No Keyframe on current frame
Orange: The property has been changed but a keyframe hasn't been set
I could not find where Blender actually documents these colors though.
