There will be no total black, but some dark shades are possible. + +Screencast shows the red colored checkmark to enable Autocolor assets. +In the lower left corner is Highlighting Inversion color which can also be set and is discussed elsewhere. + +\begin{figure}[htpb] + \centering + \includegraphics[width=0.8\linewidth]{images/autocolor-assets.png} + \caption{Autocolor assets} + \label{fig:autocolor_assets} +\end{figure} + +To change a specific clip to your own chosen color, middle mouse button over that clip and an Edits popup will be displayed. +Choose the option \emph{Bar Color} to bring up the color picker and choose a color. +You can also change the alpha value in the color picker and this alpha takes precedence over the current alpha slider bar value unless it was set to 1.0. +The color will only change after you click on the checkmark. +The \emph{Bar Color} option works in either Drag and Drop or Cut and Paste editing mode and also works if “Autocolor assets” is not set. +In Drag and Drop editing mode, if you select several clips and then bring up the Edits popup with the middle mouse button over a track, you can use the \emph{Bar Color} option to change all of those selected to the same color. + +To go back to the default colors, uncheck “Autocolor assets” in Preferences, but this does not affect the specially chosen self-colored ones as they are preserved. +To change these individually or selectively use the Edits popup \emph{Bar Color} option and click on “Default” in the color picker window. Auto-color does not honor armed/disarmed tracks. +Self-color does honor armed/disarmed tracks. + +And that’s not all! +There is an \emph{alpha fader slider bar} on the bottom of the main window on the right hand side of what is referred to as the Zoom Panel. +With this alpha slider, you can colorize your video and audio tracks to either see only the color at 0.0 or see only the image/audio waveform at 1.0. +This slider bar affects all colored areas of the Autocolor assets and the self-colored ones. +In the case when a specifically changed edit alpha value is any value except 1, the slider bar will not affect that. +Once you use the slider bar, it is activated so gets first shot at any keystrokes in the main window. +You deactivate this by simply clicking in a different part of the main window. + +As long as we are on the subject of color, just a reminder that you can also change the “Highlighting Inversion color” in Settings$\rightarrow$Preferences, Appearance tab. +This is on right left hand side of the menu more than half the way down and you can see this in the figure~\ref{fig:autocolor_assets}. +That setting defaults to white (ffffff) but sometimes this is a little bright so you can put any hex value in that suits you. + +Screencast (figure~\ref{fig:autocolor_assets_alpha}) which shows an example of the Autocolor assets with alpha set to 0.0. +In this screencast (figure~\ref{fig:autocolor_assets_alpha}), the alpha is set to show the image as well as the colors.
