You can't tint white paint to anything other than a pastel shade. The white pigment will overpower any other color you add. If you try to put in too much tint, you wind up with lots of pigment, but not enough resin. When the paint dries, it's powdery and won't last.
We actually buy a tint from Sherwin Williams called "blend a color" we buy blue to tint white to make HC blue, we have gotten it very very dark with no problems. Two things to remember, when you add allot of tint to get a really dark dark blue you end up spending more money in tint than just buying regular HC blue, also the tinted blue will fade sooner than store bought blue. But its great if you have a bucket of white that may have had a bit of yellow or something mixed in when and if you have to change colors on your machines.
Like Asphaltman and Ohio Joe we also do all of our tinting. It is a great way to use up your partial buckets of white. Our S/W dealer gives us the tint ,I guess so they don't have to mess with it. What is weird is that the same tint works for both waterborne and oil base including C/R. We have not had any fading problems at all.
I used to tint white to make handicap blue using the SW tint, but it doesn't hold it's color as well as store-bought hc blue. I once had a SW store tint yellow traffic paint until it was dark green. He had to pour out a gallon or two of yellow in order to get enough tint in there to make it the right color. The paint lasted a couple of days. It was powdery when it dried. That's why they make a neutral tinting base for colors. The white and yellow pigments in traffic paint tend to overcome any tint.
We have SW tint white for all of our HC Blue, whether latex or alkyd. Our coloration is different than any other in town. It's much brighter (but not pastel), stays bright longer, and lasts a long time (maybe too long). We simply figured out how much tint we needed and our SW rep put our formula into their computer system so whoever mixes it knows how much to add.
Sometime you have to tint: One of my customers is a nationwide general contractor and the owners happen to be rabid UNC (University of North Carolina Tarheels)(aka Tarholes) fans. When it came time to stripe their new parking area, all lines had to be done in UNC Blue aka Carolina Blue. Handicap Blue is generally closer to the much hated Duke Blue Devil Blue, so the paint for the parking area had to be custom tinted. So now the Carolina Blue parking lines match all of the Carolina Blue trucks in their fleet. Oddly enough, their logo has some North Carolina State Wolfpack Red in it.
There you go Eric, that's the way to think, keep that in mind with cleaning thinner or tip can thinners too. Keep disposal to a minimum, I try not to let any paint get bad and that is a good trick, about the time you used up that last bit of white though you'll need it somewhere .
Another idea is if you have some bad white, add a little black then use it to cover up stripes when owners want to move stalls or black something out, the grey actually blends in better then straight black on older asphalt.. Also, like I said before we just bought a jug of the blue tint from SW and then when we get a pail of off white we can throw some blue in and have perfect HC blue from "waste paint"...
