You can change colors of layer and master guides. To make it easier to distinguish between the Normal and Preview modes, you can change the color of the page background and pasteboard.

Fred4 also lets you control how close an object needs to be to snap to a guide, whether guides should be displayed in front of or behind objects, as well as the size of the pasteboard.

Guides color

On the Edit menu, click Preferences, and then on the Grid tab, select colors and dashing for the user defined (layer) guides and master guides. The user defined guides you add on the layer level. The master guides are created on the master. All Windows colors are available for each set of guides. You can also add custom colors.

Color of the page margins is dark red. You cannot change it.

You cannot set the bleed and slug area color, but you can add non-printing boxes in any color to every master to simulate bleed and slug area (if required).

Snap zone

To set how close an object must be to snap to a guide or grid, specify a value in pixels in Snapping Tolerance. Enter 0 to force Fred4 to extend snap zone to guides and grids - in that case, objects will snap only to visible guides, and it won't be possible to place them freely. The recommended value is 10 to 20.

Guides stacking

To display guides in front of objects, under View, select Front. To display guides only in front of master object, but below page objects, under View, select Front of master. The default setting is Back.

Pasteboard

Page background color

You can change the on-screen color of your paper. On the Colors tab, in Page background, select color. This color appears on-screen only, and does not affect output; it is intended only to simulate designing for nonwhite paper.
