If you want to go high-dolla, take an empty quart can to your local auto paint store.  Peruse their paint chips until you find the maroon of your dreams, then talk them into putting just the pigment mix for that color into your quart can (pigments are all dry powders these days).  Then take 'em home, mix in a quart of clear Lite-coat, and enjoy.

When I inquired locally about this ('cuz it's what Randy Powell does) they gave me a price for a quart of color that was north of $150.  I decided I'd just get a gallon each of red, white, and blue, and then claim that my color schemes were motivated by patriotism rather than parsimony.

The reason I'm being so dodgy is because there is no such thing as one color of paint -- the colors are mixed from several base pigments, and chances are high that anything that you get by mixing colors on your own (red + blue for maroon, for instance) is going to be muddy compared to what you'd get from a custom mix.  If you've ever had one of those glass bottles of Sig dope that settled out you'd see what I'm talking about (mine settled in quite distinct layers).  Someone will tell you it's a great idea, someone else will tell you what I just told you -- I'll believe whatever Billy Byles or Mark Scarborough tell you, and remember it for later.

the kink to this, if you use a blue that is on the green side, or a red that is on the green side,, you will get mud, you need a blue that is red tint, and a red that is blue tint,,
this wont make much sense unless you see an actual color bank in a paint store,, there are probably 6 blues,, and the same or more reds,, but the basic idea is, get the cleanest red and cleanest blue you can, bright crisp color, and start from there,, might need a touch of yellow to kill the purple tinge, ,but its all in what you want

Any reason why it has to be SIG Dope?   Just buy some Brodak maroon.  They are perfectly compatible.

 Yep, and it covers great.

Maybe it's a "shop around to find someone" sort of deal.

One thing you may be missing Tim, Randy gets a pint can with the amount of toner you would use for a pint of base color, My guess, its less than half a pint when he walks out the door.
if you want a Quart of toner, that is likely enough to mix with binder and resin to make at least two quarts of color, HUGE difference in quantity

Cause I have a lot of it.....
