Minute details collected at the Lundy double-murder scene will continue to be under the spotlight in court today.
ESR scientist Sally Coulson has been giving evidence at the jury trial in the High Court at Wellington.
Mark Lundy, 56, has been defending charges that he killed his 38-year-old wife Christine and 7-year-old daughter Amber in the early hours of August 30, 2001 at their Palmerston North home.
As the trial neared the end of its forth week yesterday, Ms Coulson told the jury of five women and seven men that some paint fragments found on the bodies at the crime scene matched orange and light blue paint on some of Lundy's tools.
Ms Coulson told the court there would have had to have been "some force" for the paint to have come off the weapon and embedded onto Mrs Lundy and her daughter's bones.
She agreed with defence lawyer Julie-Anne Kincade that when looking at photos of Lundy's garage, crammed with tools, that some looked aged and worn and fragments appeared to have come off them and rested in the area the tools were stored.
Ms Coulson also examined fibres collected from Amber and Mrs Lundy's fingernails, none of which matched Lundy's dark blue and yellow polo shirt.
The jury trial before Justice Simon France continues.
