Grays and Whites

I'm having a problem with my whites. I don't have a consistent white formula that I use while painting, instead I mix a new batch every time I sit down, and most of the time I use a very haphazard method of using a little of this, a mess of that, whatever looks good, etc. I'm looking for a color that is off-white, but not too yellow or blue. It's really hard to find that perfect color.

So I've been experimenting a bit with the whites and grays that I use when I paint in oils. The above are two of my favorite whites. I think I have mentioned Archival Fast-Drying White before, I really like it and use it for almost all of my mixing. For a gray horse, though, I'm trying out Archival's Tinting White. I bought this a while ago and didn't use it because I thought it would take too long to dry. But guess what? It's not too bad! It's slightly off-white, with a pearly sheen, and the consistency is really soft and buttery, which I like. Here's a little comparison of them, with a buff titanium I've been using to show how different that color can be:

I've been adding just a touch of the Buff Titan to the Tinting White, and then a smidgen of a gray mix to use for my grays. 

Now on to the grays. I also have a problem with my grays getting a little too blue for my taste. I used to use Burnt Umber and Mars Black, with a touch of a yellow ochre, but lately I've been mixing equal parts of Raw Umber and Van Dyke Brown plus a touch of Mars Black. Today I made this little chart of different mixes to see what worked best. I was surprised to see that I liked the mix with the two browns and Ivory Black. I usually equate Ivory Black with blue, but it looks pretty good to me. Mars Black is a stronger tinting color than Ivory Black, so maybe that's why.

So, what do you think? Do you have a favorite "recipe"? I would love to hear what other artists use for their whites and grays when they paint in oils.

Warm Greys

Here are a couple of warm grey color that I've been trying out recently. I like both of them.

The one on the left is Sennelier Acrylique Warm Grey, and the one on the right is Old Holland Warm Grey Light oil paint. They're both pretty similar which is good for matching acrylic colors to oils if I need to do that. They are so warm that they're almost brown in color (in fact, both these colors are a mix of browns with white). I've added titanium white as a tint and mars black as a shade on both of these for comparison.

The tints are really nice, great for highlighting, light dapples or to incorporate into the base color for white markings or a grey horse. The darker shades are great for greys again, muzzles, and also for some grullo colors. Out of the tube, these greys would make a great base color for a classic champagne (haven't tried that yet but it looks like it would work), or a dun or brownish grullo color. They're also a good base color for chestnuts, can be mixed with a darker brown, black, etc. for a variety of grayish-brown colors. Very versatile!

The Sennelier acrylic is pretty thick so will need to be watered down before use, and the Old Holland oil is thick also, so you might want to try a medium or thinner to help smooth brushstrokes. I used to hate how thick and hard Old Holland colors were, but I really like this color so I've gotten used to it.
