Does anybody know how to make your fin look pearlescent like this? It looks clear in the shade but in the light it has all these colors. I'm going to be layng up a fin panel this weekend and want to try and have it look like this
My money is on it being a clear panel. I'd say the different colors come from the foil.
To get the clearest panel lay up the panel in sections of 10 wetting out 1 lam at a time. Kick to panel slow. This will keeping the panel from getting too hot. And take forever to make.
I've had many fins with no color in them and none looked like this. Can't tell you how it's done, but I like it. Very cool.
I use a lot of automotive pearl and metal flake in projects, either as a foam stain, or in the laminating resin (or even in a coat applied before the hot coat). I imagine it could produce this affect if you added it (it comes in a very fine powder form) to your clear laminating resin while laying up the fin panel.
You can get small sample amounts (5 grams) on Amazon for about $8 that would be plenty enough for a fin. Search "color shift pearl sample" on Amazon, you'll find it.
I'm not saying that this is how the fin you posted was made, it's just a suggestion.
Awesome thanks guys, I think I'll try the color shift stuff from amazon and see how it goes. Other clear fins didn't have that same look so I figured a little something extra was done to it
I see that the very thinnest parts at the base and tip are a mauve then quickly to a blue colour, then green at either end a lot of orange in the middle.
I think it's from layering opaque colours and as the thickness changes the subtle colours.
Certainly the mauve in the middle and the green would produce that subtle blue hue. The surface colour is probabaly more red than orange but with the green behind it it looks orange.
Gentlemen... to the colour wheel !!
Might be refraction of light passing through a (translucent?) curved surface varying in thickness.

after closer inspection I think you may be right, it does look like the colors go with different layers. I already ordered the paint additive from amazon so I think I will end up using that. But maybe the next one I'll try using very small amounts of pigment for certain layers
I try to stay away from anything that will end up creating a "fishing lure" affect. Glitter, flakes, color combinations, figured wood grains that can change as light hits it are some of the things I stay away from. No sense making something that might attract the big fish.
Very good point, that hadn't crossed my mind
I'm not disagreeing with anything about the possible attraction of larger...fish, however I've seen a lot of boards and fins with heavy flake and pearl. I always thought of the "fishing lure" effect, but never heard of anyone having any type of extra attention drawn to them from it. I have a few handplanes with a lot of flake in them, and never had any type of repercussions (I usually swim out to a bit deeper water too).
I think you'll like the pearl effect, it's VERY subtle, like the photo you posted. Metal flake is what gives the flashy 70's powerboat type finishes. Maybe try a test panel and see what you think? I suppose I like experimenting more than most though.
