Dave Moore answers the question i posed ACF
Many years ago a certain famous lincolnshire carp angler advocated using Blue baits ,especially in deep water .the idea was founded on the fact that the blue end of the colour spectrum is the easiest to see in poor light.
I've only ever used blue baits once and had very poor results,
I stopped using them and found out later that the dye wasn't a food dye but an industrial dye used in printing and paint manufacture . It does certainly pay to do your research before putting a strange ingrediant into your bait .I often wonder if my lack of success was more to do with the toxic nature of the compound and not the colour.
Not having had any great experience with using blue baits ,i posed your question to my bait expert Mr Bill cottam of nutrabaits. His answer was more to do with the practical application of applying blue food colouring to the common bait mixes and ingrediants widley used.
Apparently ,it is hard to colour bait blue due to the nature of the food colouring and the levels that he thinks are acceptable under the guidelines given to him by the supplier .
If your bait mixes contain any dark pigment ,the colour has a tendancy to blend and become purple. milk protien mixes ,or soya -and - semolina baits can be coloured blue because of their naturally light pigment. However ,Bill doesn't think it's possible to achieve a perfect blue with any of the food colours he would be confortable using and supplying . So your answer to why bait manufacturers dont supply blue baits is probably due to the difficulty of ,perhaps ,compromising quality .
There are ,however some commercially available blue baits ; I believe that cotswold bait creations and CC moore do a blue pop-up. I have no experience or knowledge as to how these are made ,or if they are any good ,but somone must be confident in their formulation and effectiveness.
Carp have eyes but it's not fully known how effective they are at discerning colour . Their brains are very simple and probably lack th ecapacity to process that information . the best question to ask is ,do they need recognition to survive?If the answer is no ,then why should they have evolved that abillity ?.From an evolutionary perspective ,its betterto develop a sense that will prevent you bieng eaten.
I believe that carp can discern between different colours ,but not itn the way that we do .They see colour as shades of brightness.This form of colour perception will depend on light levels ,so this will change with depth and water clarity. Blue baits will appear dark so your lack of success may be due to a visual-recognition problem.
I personally don't bother having any of my baits coloured because i honestly do not think that it makes any difference .My interest is in the nutritional
value of bait,which will always be the ultimate attractor for long - term success.
this is word for word the answer in the magazine
Personally i'm still no the wiser as its not a straight forward answer
