Scarborough Athletic booked a 3-1 win and the three points that sealed promotion to the Evo-Stik Premier on Saturday afternoon.
And the victory pushed them a little closer to second in the table behind runaway leaders South Shields.
Boss Steve Kittrick led his side over the border and into Lancashire with the same starting 11 as the win at Colwyn Bay on Tuesday night.
They started the game with the advantage of playing down the steep slope, but they were soon caught napping at their end of the incline.
The right side of the defence vanished with six minutes on the clock and Alex Curran drilled in a low cross that Tom Pratt converted.
Boro took a breath and hit back though, despite not even having a shot on goal.
Max Wright felt the force of Lee Pugh's clumsy shove in the box and James Walshaw took up penalty duties to roll home.
The pace of the game took a stumble after this, with Colne looking to more likely to re-shatter parity.
They went very close to this when Jonathan Hodgkinson's header wrong-footed Tommy Taylor, but finished up on the wrong side of the post.
When the second half began, Boro began to take control of the fixture, roared on by a boisterous visiting support.
Despite playing up the hill, Boro soon had Colne pinned back in their half.
And they were finally rewarded for their efforts when Walshaw's powered a header onto the bar and Wright poked home the rebound from close range.
Colne almost grabbed an immediate equaliser when Gary Stopforth crept onto a ball into the box, but his deflected effort bounced just wide.
Boro gathered their thoughts and then struck the killer blow.
Walshaw, who had been a constant threat all afternoon, marauded through and lifted delightfully over keeper Hakan Burton and into the net.
Colne came again and Taylor was forced into a superb one-handed save to push away a sweet drive from Curran.
But Boro stuck to their task in style to pick up the result they wanted and start the celebrations.
