Different colours for different posters

[summerainbow]

I have sight issue and dyslexia.
At the moment I have OP post in one colour aand mine in another so I can scroll though a thread and just read the update s or comments after my posts.
But when it come to long chat threads like the dating thread if there was option for me to chose ( important I choose as I can see some colour on some colour) a different colour for different posters so I could follow their posts.
What happens is I start reading then give up as I just cannot follow it.
