Just curious as to the colours and light(s) used.
I was taught that the darker the colour of the
gel the quicker it will
fade.
The
focal length of the light will also influence this (I may not be wording this incorrectly, but essentially, the closer the
gel is to the lamp the quicker it will
fade). As will the duration of use.
To my understanding this means that because of the nature of darker colours, you have to pump more light through them, which deteriorated the
gel. By using them in applications where they are close to the lamp or being used for extended durations, you will speed up this progress.
I have seen 181
gel have to be replaced after a single show because it was used in a 'stubby' Par64 and used as a
wash.
I probably haven't addressed this all that well but I am sure that someone will
pick up on my efforts and expand on them or describe them in a better manner than I have (please).
