mixing colors question
« on: March 29, 2011, 07:55:53 PM »
Here's a question for you guys who are good at mixing colors.  If I started with Brodak platinum gray, what should I mix into it in order to get it to the same color as brodak silver?

Reason I ask is I don't really care for platinum gray, and I don't want to use silver for the new plane, but I really like the color of it.

I'm not sure you can get there from here.  Silver paint is as much an effect as a color -- the paint literally has little flakes of metal (usually aluminum) in it.  At a guess, I'd say the platinum gray is a metallic gray, meaning it'll have metal, black pigment, and at least some white base.  With the black in there, there may not be anything you could add to it to get a silver color.

Why don't you like the silver?

The problem with electric is that once you get the smoke generator and sound system installed, the plane is too heavy.

Be very careful when mixing silver with anything. It has more of a blue tint than actual silver.

Waaay back in 1967, I had the pleasure of meeting a young guy at a meet in New Bedford, Mass. He had this   absolutely beautiful candy apple red modified Nobler.  I asked him how he got the candy color. He told me in detail, very friendly and very patient with all my questions.  A few weeks later, I was painting my second Nobler and decided, dope fumes abounded, that why do  silver then the red, why not just mix them. I did and got instant metallic purple. 

A few months ago I remembered this and had to make some metallic purple and mixed silver with red. Bingo, still works.

PS, the young guy was Bob Hunt. H^^

Ty,

I'm not looking to mix colors into silver, I'm looking to see what colors I should mix to get silver without the metallic in it.

Tim,

I really like silver as a color, but it's just hard to work with, you have to be very careful when pulling up the masking tape in case any paint comes up with it.  Also it shows EVERY SINGLE little flaw in the woodwork.  Like I said above, if I started with Brodak Platinum gray, what other colors should I mix to get the same "color" as the silver (so that I won't have the metallic in it)

Matt,

You can make silver by using silver paste (Aircraft Spruce carries it). It's not metallic (in that it doesn't have flake or anything), but silver, like gold, is a metallic color; by nature metallic. So you can't really get non-metallic silver. You can get silver without flake or sparkles, but it will be at least somewhat metallic.

If you are looking for a base color like silver that still pops, you can look at various off whites or using gray with some silver paste in it to make it more silver like. It's the silver paste that can make pulling tape tricky. It helps if after you shoot the silver you lock it down a bit with a coat of very heavily thinned clear. But it only makes the problem better, it doesn't cure it.

I once shot a plane with a car color. A BMW color called Cappuccino Frost. Sort of a light cream metallic. Cool color, but it was heck to pull tape up on. Found out later from the auto paint guy that it had quite a bit of silver paste in it.

get friendly with your local auto paint supplier.

They will ( if your nice enough ) allow you to come around the back and mix the custom colour infront of you.

Thats what I do - I dont bother messing around with it - for the small amount I pay - the custom service is wonderful. They also know waht they are doing re: mixing it really is an art.. you want a red a little more vibrant they add " a weird orange " its very strange but it works everytime.

Matt:

This is what I meant by "silver is more of an effect than a color".  By itself, silver is just a bluish gray, just as, by itself, gold is just a shade of yellow.  What makes it silver is that it reflects the ambient light: in a room with yellow light it reflects a bit yellow, outside it may reflect the clear blue sky, etc.  Moreover, even if you can't make out the individual particles of metal, it sparkles -- and no gray is going to do that.

But it still won't really be silver -- although maybe it'll be close enough.

One thing I've learned in over twenty years of doing engineering on electromechanical systems is that sometimes it doesn't matter whether you solve a given problem with circuitry, software, or mechanisms -- that problem is just going to make you bleed, and while there may be a few different ways of solving it, they'll all hurt.  Often, you'll have one or two nasty ways to solve the problem, and a whole plethora of possible solutions that'll either hurt worse or won't solve the problem at all.

In those cases you just heave a big sigh and you pay your dues.  It sounds like getting a good looking silver may be one of those cases.

Hi Tim,

I see what you're saying now. What I might do like PJ and Randy have mentioned is find a car color that is what I'm looking for and either get it from DuPont Chromabase or have the paint supplier mix it for me.

I went to my paint guy today and got bad news. What I normally do is give the guy a color number and have him mix it without urethane binder. Take it home and replace the binder with clear dope (as a binder). Toners are neutral and will mix with anything. Now the bad news.

They guy said that more and more, elements of the ingredients are coming pre-mixed. This is to insure consistency across paint shops and so closer matching to original colors. Problem is, those pre-mixed ingredients are using a urethane carrier so some color just can't be mixed with dope. So the days of getting my local paint shop to mix up colors for me are probably going to come to an end soon.

Well, back to experimenting with substrates that are at least somewhat compatible with urethane.

Here's the color I mixed that is going to be the base color on the new plane!  It's a bluish gray, more blue than gray, but I think it's gonna look really nice once it goes on the entire airframe.

2 cans of platinum gray, about half a can of insignia blue, and some black made this color.
