Using the Input Button to Take a Color
You use the Input button to take a color from an application and add it to
the displayed palette. Graphics applications often have several color properties – foreground
color, background color, fill color and so on. To take specific color properties
from an application, press the Input button while holding down either the 'shift'
key, the 'option' key or the 'command' key. Use the Actions Tooltip or Actions
Summary panel to determine which input button and modifier key combinations
will take which color properties from an application.
The Input button cannot take colors from all applications. For this reason,
the Input button will appear disabled when an application doesn't support
the Input button and enabled when it does. If an Action cannot take a color
from an application, Tangerine will alert you to this issue by beeping.
Colors taken from applications that have a transparency or an alpha channel
are added to a palette as opaque colors.
You can avoid having identical colors in your palettes by selecting the 'Avoid
identical colors in a palette' checkbox in the Palettes Manager window.
If you try to add a color that already exists in the palette, Tangerine will
identify the swatch in the palette when the input button is pressed. For more
information see Avoiding
Identical Color.
You can customise how the Input button takes colors from an application in
the Actions window. For more information see The
Actions Window – An
Overview.
Tangerine has additional methods of adding colors to palettes. For more information
see Dragging and Dropping a Color from a Color Well, Dragging
and Dropping Hexadecimal Color Syntax, Sampling a Pixel Color from Screen and Creating
a New Color and Setting its Color Values.
