Assuming your question is asked with good intentions,
it is !

It does take time to answer questions like this, so thanks would be in
order rather than a wise-ass "alright, so, how do you explain..."

You are right there and there was no intention of being unpleasant, please
just consider the fact that I am not a natural english speaker.
Even if I try to do my best when writing, I now realise you could have felt
upset reading this.
I appreciate your remarks and enjoy that people like you bring on-topic
knowledge to the group in the middle of all those crosspost trash.
Thanks again for your answers.
However, apart from the red one, I still wonder why those other colour
stripes could be different ! There must be an answer somewhere.
