I once tried defferent colour Maggots,the so called party blend type,some very bright colours and dark just to see what the carp was taking a likeing to,i first tried the dark coloured ones that being Blue,Green,Purple and the results was not that good just the odd take in the margin with them but when i switched to the bright colours Red,Pink,Yellow and White the results was defferent,i had loads of takes off these and the best colour i found was the fluro Orange,i had my best catches on those colours and the brighter the better i found.
This was done on a local com water to me that is very coloured in fact you can not see your hand more than a foot below the surface yet these colours was catching now if colours don't play a big part in fishing for carp i find it strange that these worked so well,it is as though the carp can see these bright colours but not so much the dark in such water conditions,i find it very strange that some think that red goes invisable underwater when in fact all it does is change colour to Grey and so on because of the lack of ultra violet rays,could it be that it is the opposite to this that infact it is the dark colours that dissapear in such waters and the fish can not see them so well?..like i said i carried out a short trial with these maggots and i was shocked by the results and there is no doubt in my mind that fish/carp can indeed see bright colours in cloudy waters and in my opinion it is through the colour change that happens that the fish come to accecpt has feed/food.
