A heartbreaking note written by slain Victorian boy Luke Batty reveals why he loved the colour yellow so much.
Family, friends and schoolmates arrived at the funeral service - most wearing something yellow in Luke's honour.
It was his favourite colour, and it is the colour of his coffin.
Luke was killed last week by his estranged father, Greg Anderson, after a cricket practice at Tyabb, on the Mornington Peninsula.
Police fatally shot the knife-wielding father after failing to subdue him with capsicum spray.
Hundreds of people arrived at Flinders Christian Community College on Friday morning to remember the 11-year-old.
A heartbreaking poem by Luke, printed in the funeral program, detailed why he loved the colour yellow.
"In the natural world yellow is the colour of sunflowers and daffodils, egg yolks and lemons, canaries, bees and bananas."
"In our contemporary human-made world yellow is the colour of Sponge Bob, the Tour de France winner’s jersey, happy faces, post-it notes and signs that alert us to dangers or caution.
"It’s the colour of happiness and optimism, of enlightenment and creativity, sunshine and spring.”
While the service is being held in the school chapel for close family and friends, it is also being screened in the gym, where other mourners are attending.
Luke's grandmother Josephine Batty spoke of his delightful sense of humour, but said that "his death came too early".
"We were so blessed to spend five weeks with him last Christmas and January."
Head of Flinders' junior school Greg Partridge said Luke was a confident boy with a positive impact on students around him.
"Teachers found it hard to discipline him when they were laughing at what he had just done," he said.
"You will be missed dearly Luke."
Eulogies also told of how Luke was a quirky kid who loved cricket, and wrote love letters to girls.
A private family cremation will follow the service.
The family have requested donations to an organisation for children affected by violence instead of flowers.
