watching Sariel's video of him talking with Technic designers it seems obvious they read the forums here, know exactly what people think and want from sets etc.
they even mentioned colour vomit and address why the Red and Yellow axles were introduced....as we speculated it was to give kids an easier time to find the parts when they dump hundreads of pieces onto the floor or into a box etc.
one must also assume that the new axles colurs give designers more choice, colour co-ordination etc. - but the complaints here seem rather silly, in that it is very easy for us guys to simply swap out coloured axles for whatever colour you think is right.
i have Black 3L and 5L axles and often use them to colour co-ordinated certain sections when i am building a set, in fact i have many parts in many rare colours to do just this, most Technic parts exist in multiple colours outside of Red, Black, Yellow and LBG....so i think the complaints about colour vomit are null and void...
IMO.
