Natural wood colors range from yellow to red to tan to brown to grey or black. All these shades can be obtained by various combinations of only four color pigments: white, red, yellow and black. Dry powder pigments which are fully compatible with our products (universal liquid color concentrates are not) are available.

​

Smith's Fill-It parts A and B should be mixed together as the product instructions recommend. Then, as each pigment is added, color will develop with mixing. Continue mixing until no further color change is seen with continued mixing. Only then add another color pigment.

​

Add a small amount of dry white pigment, perhaps a tablespoon or two for a mixed quart. Next, a small amount of red or yellow may be added to approximate the red-yellow balance. Then add a little black to darken to the desired color. Then, try a little more red or yellow if needed. Should the mix be too dark, add some more white to lighten the mix. The total amount of white pigment needed may be comparable to or much more than the total amount of all the other tinting pigments, as a VERY rough guide. Very dark woods will need less white, and will usually have more red than yellow.
