I've posted about this before but am just looking for a definitive answer on a putting issue.
Being colour-blind, I can't differentiate between the various colours on the putting grid, but I can accept that now, and have learnt to do without the information it gives me.
What I can't figure out are the different colours on the aim line. Sometimes it's obviously black, but often it changes to other colours (blue?/red?). This appears to occur more frequently with longer putts, but does it just signify an uphill or downhill putt or am I missing something?
I'd also like to know how other colour-blind people overcome the obvious disadvantage when putting, as I know I can't be the only one. Statistically, about one in twelve men have it, albeit to varying degrees, and slightly fewer women.
I got tested recently for the first time in years, and apparently mine is as bad as it gets.
Thanks everyone.
