Schematics On White Background

I don’t think there is a list of recommend settings for changing the color of objects when background is white – at least I’m not aware of such a list.

To change the colors you can use the solution described in the below article.

What layers and purposes (lpp's) are used by schematic composer/editor to draw objects? 

As solution says, you need to modify the display packet information in the display.drf file – look for drDefinePacket- and change the color for the desired packet.

The article also includes a table with the objects and the layer purpose pairs (LPPs) that are currently used. For example , the LPP that is being used for selected objects is ‘hilite,drawing’ and the packet name is ‘hilite’.

There is also the GUI way to change the colors for the LPPs. In CIW, go to Tools->Display Resource Manager…In the form that opens, click on Edit… button.

Set the GUI as below- select to see all LPPs. Then select the desired LPP and change the Outline Color or/and the Line style. Then select “Modify Current Packet” to apply the changes to the schematics in your current virtuoso session- you’ll need to press ‘F’ in your schematic to load the changes.

To save the changes as a file called e.g display_mod.drf, select File->Save in the GUI above.

To load the modified display_mod.drf file in a virtuoso session use the below command in CIW:

drLoadDrf("<path_to_display.drf>/display_mod.drf")

Or if you want to apply it permanently add the below in your .cdsinit file.

ddGetObj("pdkLibName")
drLoadDrf("<path_to_display.drf>/display_mod.drf" nil)

I also filed (only a couple of weeks ago), enhancement CCR 2346074 to automatically adjust the colours when the background is changed so that they remain visible (ViVA already does something similar and that's quite effective). If you want something similar, you should contact customer support and ask for a duplicate to be filed.
