Edit Palette
This dialog is made to change single entries of the current color palette
and can be opened by double clicking on entries of the
workspace color palettes or the
menu Colors or the toolbox.

Foreground and background color are defined by left/right clicking on the
color boxes. Their values (palette index and RGB) are shown below the color table.
To change the color of a certain palette entry just double-click and a
color dialog appears.
You may also use the little button on the left side of the "Foreground" label
to open an online color dialog that allows immediate color definition. Click
on the button again to close it.
Ramp to allows you to create a smooth color ramp from one
color to another one. To do this leftclick on a color where you want to start
ramping. Hit the Ramp to button. The mouse cursor becomes a crosshair. Now
leftclick on a second color to calculate a ramp to.
Rampmode is used to define the color space where the ramping
is to be calculated. You may select from HSV or RGB which yield different
results
Copy to allows you to copy a color value from one palette
index to another. To do this leftclick on a color where you want to copy the
values from. Hit the Copy to button. The mouse cursor becomes a crosshair.
Now leftclick on the color you want to copy the values to.
Swap with swaps the color values of two palette entries.

Invert inverts the color values of the current foreground
color.
Gray makes the color values of the current foreground color to
a gray value.
Undo makes the last change undone.
To Gradients takes you to the gradient editor (see descriptions
for the Gradient Editor).
