Choose the color from the Color menu.
To use a tint of the color, choose a tint value from the Tint menu. If the value you want doesn’t appear on the menu, choose Other from the menu, enter a tint value. Click Set.
If an object isn’t visible after you assign it a color, make sure that the color isn’t in the Invisible scroll list in the Define Color Views dialog for the current view.
You can also assign the same color to all objects in a document.
