TPDesign4 Touch Panel Design Program
Using Custom Palettes to Enable Color Schemes in G4
PanelBuilder
TPDesign4 v2.4 (or higher) supports creating and saving multiple custom color palettes within a
project. Custom palettes can be used to enable the Color Schemes feature in the G4 PanelBuilder
application.
Color Schemes allow you to apply different color schemes to an entire template (in G4
PanelBuilder), without having to edit the buttons directly. For example, you could create a single
template file with four different color palettes that would allow you to use the same template to
quickly produce four different variations on the design - one color scheme for each season.
Using custom palettes to create Color Schemes requires the use of both TPDesign4 and G4
PanelBuilder: Custom palettes are created in TPDesign4, and saved as part of the TPD4 project.
TPDesign4 is also required to export the project as a G4 PanelBuilder Template (*.TPT). However,
the Color Schemes feature is applied via the Project menu in G4 PanelBuilder.
Not all TPD4 projects support the Color Schemes feature in G4 PanelBuilder. In order to utilize
Color Schemes in G4 PanelBuilder, the TPD4 project must meet several requirements before being
exported as a G4 PanelBuilder template file (via the File > Export as G4 PanelBuilder Template
option):
 The project must include at least one custom palette (in addition to the default palette).
 The project must include one preview image for each of the custom palettes that are
included. These preview images are used to display the color schemes that are available
for this template in G4 PanelBuilder.
 Note that if the exported project does not meet these requirements, the Color Schemes
feature in G4 PanelBuilder will be disabled for this template.
 While it is not an enforced requirement, in order for the project to actually make use of
multiple palettes in G4 PanelBuilder, the buttons in the project must use the border types
that come with TPD4 (as opposed to a custom image that defines the button's look).
When a valid TPD4 project file is exported as a G4 PanelBuilder template, and then opened in the
G4 PanelBuilder application, the Project > Color Schemes option (in the G4 PanelBuilder
application) allows you to apply different color schemes to the template with a single click.
You can also use Chameleon Images in conjunction with custom palettes to further
enhance the use of Color schemes in G4 PanelBuilder.
