How do I Create a Color Picker Swatch?
This lesson will show you how to make a color picker swatch.
Create a Graphic

Select the Graphic tool (1) and draw a square graphic on a stack (2).
Make Graphic Opaque

Open the property inspector for the graphic and set the Opaque property to true.
Edit the Script

Open the script editor for the graphic and enter the script shown below.
The script uses the answer color dialog to display the system color picker (1). The backgroundcolor of the graphic is passed in as the default color to display in the color picker (2). The color the user selects is then assigned to the background color of the graphic (3).

## If user didn't cancel then assign background color
## to chosen color
if the result is not "cancel" then
put it into theChosenColor
set the backgroundcolor of me to theChosenColor
end if
end if
end mouseUp
The Script in Action

Switch to Run mode. Clicking on the graphic will now display the color picker.

Choose a new color and click OK.

The graphic is now assigned the new color.
