As reported in later editions of last night's Evening Times, labourer Alan Storie, 26, was convicted of murdering David Findlay, at Toryglen Road, Rutherglen, on June 29 last year.
At the High Court in Glasgow judge Lord Bonomy sentenced Storie to life imprisonment and ordered him to serve at least 16 years behind bars before being eligible for parole.
Storie told police who arrested him: "He'll never call me a ginger-heided b****** in his life again."
The High Court in Glasgow was shown CCTV footage taken at the waiting room in Cathcart police station, which revealed Storie making the remark.
Mr Findlay, 41, died in a pool of blood. His windpipe was cut through and his carotid artery and jugular vein were severed.
Jailing Storie judge Lord Bonomy told him: "Nothing I've heard here or during the trial can begin to explain the callous and vindictive attack on David Findlay, essentially slashing him outside his own home."
The court heard that a row developed after Storie went to see if Mr Findlay wanted to play on the X-box with him and was asked to leave.
Both men had words outside the flats, which included Mr Findlay making derogatory remarks about the colour of Storie's hair.
The Crown said it was a this point the fatal blow was struck and Mr Findlay crawled back upstairs and lay dying outside his flat.
But Storie claimed Mr Findlay banged on his door repeatedly, and he thought he had a dagger. No weapon was found.
Frances McMenamin QC, defending, told the court that Storie was bullied at school because of his hair colour.
She added: "These experiences have clearly had a profound impact on him."
