If a MacDraw II document has at least one color other than black and white, MacDraw Pro creates a new color palette with only those documents colors in it when it imports that MacDraw II document.
It names this palette the MacDraw II document name and automatically makes this the active palette. When you click on the color palette icon, you may see a fewer colors than in the default Claris Colors palette.
To use the colors in the Claris Colors palette, tear off the color palette pop-up, then select the Claris Colors palette in the View menu.
