Look in preferences. The colour indicates the type of material ie, audio, video, stills etc. You can customise these to suit you personal tastes.
Well, first of all, different types of clips have different label colors in the project panel, and that carries over to the timeline.
The edit/preferences settings allow you to change the colors under Label Colors and Label Defaults.
Then, on the other hand, there is the bug that was reported: http://forums.adobe.com/message/4069469
Thanks John... but first thing I did was look at the labels in Preferences - the clips are the same media type.
Steven, thanks for the reply, I had a look at the bug report but I dont think its the same thing. The clips are R3D files merged in Premiere with an audio track.
Its odd because the colour changes seem to mostly corresponde with scene changes in the film but when I do the same meta data entry on another project (ie. adding scene and description notes) the colors are the same
The blue in the middle are clips with both audio and video.
The purplish clips next to them (Violet) are clips with just video.
The greening underneath is a nested sequence.
The pinkish (Rose) are stills or in one case, an Adjustment Layer.
Well...I'll be...ya learn something every day...
Did you know that Jim or did you work it out just now?
(I dont think I have even seen or noticed any color on any clips at all before)
