This is getting very interesting...

I would assume that there are so many variables on the conditions and taking into account rivers, creeks versus estuaries etc and, at different times...

The first pic of Shady I posted, you could have cast Jeff's discount card in. It was filthy but no matter what you cast, you hooked up. I know Barra are more voracious in the build up/breeding/run off season and any rushing (local) water would be an attraction to them - if you were local and only had a pond to swim in.

Harbour Arms with big current/wind/heat etc, I believe are a different story all together up here.

I figure that if I were a soft snack Mullet I would not be hanging on the edges or in the turbulence of windy water (shallows) - it's hard enough getting beat up against the rocks or the bank before you get eaten I'd imagine and I've never hooked up in those conditions so I just go trolling out from the edges a bit where I suspect the bait retreats to - as rough as they can handle and in fear!

I'm pretty confident in saying if it's windy and choppy you just have to fish deeper water where the bait move to from the rough edges, at least in the shallows of Darwin Harbour arms.

In saying all that, I had a small Barra grab the end of my finger one night when I reached over the transom to rinse my fingers. I jumped in fright and the bow waves - at least 20 of, departed from the back of the boat at great speed.

The clue... they were attracted to the trickle of the live bait tank in dead silence while we had livies strategically positioned for only a couple of fish!

Sneaky indeed. :fishy:

Finally found proper scientific research to support the "missing link" results that I found and that Matt published. Its not an easy thing to publish backyard/citizen science research and I thank Matt for his vote of confidence in doing so.

Scientific stuff was carried out by Mayke Stomp at University of Amsterdam in 2008 and published in 2014.

The image had this caption.

The underwater light colour in (a) clear oceans, (b) coastal waters of intermediate turbidity and (c)
extremely turbid lakes. With increasing turbidity, the light spectrum is shifted towards red wavelengths.

Remember the image I showed in Matt's article with the Xs on it? And the advice to "follow the X" as the water got murkier? Here's the real scientific support for that advice.

This thread is titled "fluorescent orange..and contrast" but it's a lot more than fluro orange.

AND, we haven't even touched on contrast yet.

There'll be some more to come about contrast.

A bit more info about colours underwater in dirty water.

Dirtier (higher turbidity) water means that light penetrates less and that the light that does penetrate best is red (follow the X as in previous posts).

In water that's stirred up by high tidal run, I look for areas with less run (barra like to conserve energy) which usually means on the edges of headlands, points and snags.

But especially around rock bars or rocky points.

To me those areas are shallow with dirty water and a no-brainer for a red/orange shallow diving lure. Enter gold bombers etc.

The other feature of high tidal run is that the murkier water is interspaced with patches of cleaner water. Bit like a run-off with clean/dirty colour lines but in this case spread all over the creek/river or rocky point. Multiple colour lines.

That's also a sign that a 2 colour lure is odds-on to do well (providing you pick the 2 best colours).

I went for red (dirty water) and green (for the less murky patches of water). I consider red and green as the best combinations for an all-round lure. R and G are opposites on the "colour wheel" and are perfect contrasts with each other.

The only colours that I play with now are all fluorescent. I reckon I've got the local market cornered on fluro spray paint, grey undercoat and fine steel wool.

It feels strange at times, getting stuck into $25 - $30 brand new Rapala lures with steel wool to scuff up the surface for an undercoat to stick to.

Even stranger to spray paint such a beautifully finished work of art. They are real works of art and a fashion statement but the colours are all wrong for dirty water fishing. They don't have much in the way of dirty water where they're designed (northern Europe) and what we see in Aus from Rapala are lure colours for clean water .

Here are some Rapalas that I've re-painted for dirty water use. As a painter, I'm no Rembrandt. More an impressionist like Picasso (you have to look beyond the paint job to find the real beauty).

In other words, I can't paint. I use a spray can, some masking tape and a sense of humour. I paint to attract barramundi not art lovers.

Anyhow here are some examples of red/green shallow diving Rapalas.

I've mixed up the colour patterns to avoid the traditional horizontal combinations. I reckon that horizontal patterns (which is what lure makers tend to mostly use) only gives a red or a green option depending if the fish is above or below the lure.

I've also tried a vertical stripe combination and the one that seems to cover any angle is the spiral pattern. Thinking about a spiral colour pattern to take out depth differences, it seems so obvious but I've never seen one from any of the lure makers. Always the traditional horizontal sometimes with a few vertical squiggly black or red lines.

So far I've tried the fluro R/G combination on 5 trips with 2 different friends and the results are good. 10 barra/king for me on RG (also lost a few barra) and 1 barra on a grey/white combo for 1 friend. Other friend gave up on 3rd outing and started using RG (nuclear chicken) soft plastics for 2 king. They weren't fluro plastics. He commented that he didn't want to be seen using "ugly" lures. I think he's an art lover.

Looks promising but still a little way to go yet before I call it a huge success.

Note that the fluro green is real green(not chartreuse) and the red is real red (fire engine) and not pink/orange.

Never thought about spiral colour pattern?

You're right. Getting you guys thinking IS the aim. I'll give you the best info I can (sometimes a bit out there but always soundly based) and hope that you guys can put it together yourselves.

Got some info on contrast which is the "guts" of what this is all about.
