PETER JACKSON believes Town now have a strong platform to win the next two matches.
"Beating Colchester is a massive confidence booster for us," he said.
"They'd had 20 wins out of 23 games before this, and only one defeat, and it was a big pressure game for us, but the lads came through.
"We had some good luck, which we've not had recently, and I was delighted with the clean sheet.
"Once David Graham scored the second goal I also thought we were comfortable and, in the end, we thoroughly deserved to win."
Nine Premiership clubs were represented at the game - Birmingham, Bolton, Sunderland, Blackburn, Villa, Chelsea, West Brom, Boro and Wigan - in addition to five from the Championship (Wolves, Norwich, Leeds, Sheffield United and Cardiff).
"There were lots of pluses and, while we know we can improve, let's just enjoy the fact we've beaten a side on a tremendous run and moved up the table again," added Jacko.
"We've now got a platform for the next two games and the target, obviously, is to try and win them both.
"We were disappointed with our last away performance at Tranmere, so we've now got the chance to go to Blackpool and be really positive."
On selection, he said: "I thought Gary Taylor-Fletcher was outstanding.
"It was a difficult decision between him and Danny Schofield but I went for Fletch and he was excellent."
Jackson told the press there had been no fallout with Schofield, whose contract talks have stalled.
"I haven't fallen out with Danny or his representatives," he said. "The talks are ongoing and hopefully we will get something sorted out, but we haven't at the moment.
"I will continue to pick Danny. There's no use me sulking or Danny sulking because he's a contracted player until the end of June and we've a lot to play for."
