palette:scheme-dialog

Launches a dialog for previewing all the ColorBrewer color schemes.

Use the leftmost pulldown menu to select the scheme type: “Sequential,” “Divergent” or “Qualitative.” Use the next pulldown menu to select a named scheme. Finally select the number of colors. The maximum number depends on the color scheme. Use the Copy button to copy the scheme information into the clipboard. This information can be pasted into commands such as palette:scheme-colors. The Close button can be used to close the dialog.

Example:

  palette:scheme-dialog

  ;; In the dialog the user selects scheme type "Divergent," the scheme named "Spectral," and the number 3, and clicks the *Copy* button.
  ;; In the Command Center the user types "show palette:scheme-colors " and then pastes the clipboard contents, and hits *Enter*.

  show palette:scheme-colors "Divergent" "Spectral" 3
