Blue: You can use this control to adjust the blue content in the colour. In addition you can enter a blue
value as a hexadecimal number.
Alpha: The alpha value controls how “opaque,” or transparent, the colour is. An alpha value of zero
would effectively make the selected element invisible. Correspondingly, setting the alpha slider to the
far right (value “FF”) would produce a solid colour that completely hides elements beneath it. To see
some of the selected element’s background “through” the element, choose an alpha value somewhere
between these two extremes.
The palette section: Below the colour chooser controls there is a palette tool from which you can
quickly call up colours. Clicking on any of the palette squares display a pop-up menu (Fig. 2.3.3). You
can choose to assign the palette colour to the selected UI element, or alternatively replace the palette
colour with the UI element’s colour.
Load colour scheme...: Load a previously saved colour scheme. When this button is clicked, a stan-
dard le-requester dialogue-box will be shown. From this box you can navigate to a previously saved
colour-scheme le on your hard-drive.
Save colour scheme ...: Save the current colour scheme. When this button is clicked, a standard le-
requester dialogue-box will be shown. from this box you can select a le-name and a path under which
to save your colour scheme. Changes made to the colour editor are remembered between sessions,
but it is still a good idea to save your scheme.
Preset schemes...: Click this button to access a collection of preset colour schemes.
Undo: If you edit an element’s colour, but are unhappy with the result, you can use the undo button to
return the element back to the pre-edit colour.
