Hello All,

I've just submitted a bug, explaining a weird case when the bond color fades sometimes, if the picture is generated based on 2D coordinates retrieved from a file and not generated via StructureDiagramGenerator.

https://sourceforge.net/tracker/?func=detail&aid=3295256&group_id=20024&atid=120024

The test case is intentionally minimal (two benzene SDF with slightly different coordinates, generating pictures with different bond colors) , but there are many more examples at OpenTox services , e.g. http://apps.ideaconsult.net:8080/ambit2/dataset/9 - note the pictures with gray bonds.

The effect appeared when upgrading from JChemPaint 3.1.3  to cdk-1.3.8 + cdk-jchempaint 18.

Best regards,
Nina
