Jail-Maze Crescendo: On charting a dot-path home

You wake up and find yourself lying on a cold, stone floor. Every part of you aches after your fall through the trapdoor. Ahead of you stands a wooden door, beyond which lies the labyrinth.

Your captor’s instructions were clear:

Find your way through the maze, following the path of words and coloured dots. Reaching the end, however, does not guarantee your safety. To be given your freedom you must shout out one final password – specifically, a colour. Fail, and your bones shall remain in the labyrinth for all eternity…

Wishing you had something warm to keep the freezing air at bay, you set off on foot, twisting this way and that, hitting dead end after dead end. But gradually you begin to realise what is going on here, and you pick up pace, moving faster, jogging, running, sprinting down the corridors, hungrily searching for the route that will bring you freedom.

Finally, you reach the exit, and with all the strength you can muster you bellow out one word, the natural crescendo to your journey through the maze. The locked door opens… and you are free at last…

TASK: Find your way through the maze and deduce the ‘colourful’ password that will grant you your freedom.

With apologies to solvers with colour-blindness, no colour transcript is provided (deduce from this the relevance of colour to the solution of this puzzle); however, this should not prove too much of a disadvantage since even solvers without colour-blindness will need to resort to using the same identification tools in many cases.}
