Hi Jeff,
Thanks for the great comments, glad you like them :)
Of course if there are any specific colours you'd like to see, then its not a problem to work those up.
My thinking behind them was this based on their psychological implications;
BLUE (17 & 23) - Intelligence, communication, trust, efficiency, reflection
LIME GREEN (17) - Harmony, balance, reassurance,
ORANGE (23) - physical comfort, warmth, security, passion, abundance
And for those reasons I thought they would work well for your logo.
In terms of symbolism behind the icons;
17 & 23 represent different entities (the different coloured elements) i.e. congregations & communities, coming together and uniting as one team/unit, giving an entire, a whole, closing the circle - so to speak.
Hope that made sense :)
Regards
Angus
