Concrete Color Formulas for Stone, Tile, Bricks, and Pavers using Portland and Sand, or Premixed Sand Mix and Made with Olde World Stone & Tile Molds
All of the formulas are based on what we consider a full batch, and are designed for mortar mixer and vibrating table utilization, which is normally the case with our Commercial Producers. The batches are based on using full 94 pound bags of white Portland cement, five and a half, five-gallon buckets of course sand, colorant, additive and Olde World Molds. For smaller half, or quarter batches, etc., just reduce the formulas by 50% and 25% respectively, or the appropriate percentage of the size of the batch of concrete that you want to make. As for the concrete additives that we recommend, just follow the instructions on the label, or if you are a Commercial Producer, the measurements are in your Training Manual.
The different color formulas listed here will give the colorant measurements only. The white cement, additives and the sand will be per the standard measurements as listed in “Section 3.7.7 MIXING”, in our Manufacturing Training Manual. If using standard gray Portland cement, the colors will be effected slightly and may end up darker than you may have anticipated. They will not be too dramatic though, as standard gray concrete is normally fairly light in color anyway.
If you are using premixed bags of concrete or Sand Mix, cut the coloring by about 50% when using an 80 pound bag of concrete as there is not as much Portland in bags of premix concrete than in Sand Mix or our Portland formulas. Our main concrete "Cast Iron" additive dosage is one ounce per 80 lb. bag of premix concrete, or four ounces when using full Portland cement batches that will normally yield between 85-90 square feet of cementitious tile at one-half inch thickness. To figure yields of other sized molds per batch, use the 85 square feet at 1/2" thickness as your base number, and multiply or divide accordingly. Or you can go to one of our Articles on this website for the answers and formulas.
The formulas listed below will give you the colors as illustrated in the installation photos of our on-line website catalogue. Most started with white Portland cement.
WHITE-----------------------No colorant added. Use straight WHITE Portland cement.
ANTIQUE WHITE---------Umber - 50 grams, Yellow - 50 grams per 94 lb. bag WHITE Portland cement
IVORY------------------------Umber - 100 grams, Yellow - 100 grams per 94 lb. bag WHITE Portland cement
SAND-------------------------Yellow - 40 grams, Umber - 80 grams per 94 lb. bag WHITE Portland cement
BERRY-----------------------Red - 20 grams, Umber - 4 grams per 94 lb. bag WHITE Portland cement
CORAL-----------------------Red - 160 grams, Yellow - 100 grams, Umber - 132 grams per 94 lb. bag WHITE Portland cement
SALMON---------------------Red - 266 grams, Yellow - 266 grams, Umber - 266 grams per 94 lb. bag WHITE Portland cement
MILLER'S HAZELNUT--Brown - 500 grams, Red - 220 grams, Yellow - 550 grams in WHITE Portland cement
WE WILL BE UPDATING THE COLOR FORMULAS AND ILLUSTRATING THEM WHEN USING STANDARD GRAY PORTLAND CEMENT AND SAND, OR USING A PREMIXED "SAND MIX", WHICH IS BASICALLY THE SAME THING, SO YOU CAN USE THE LESS EXPENSIVE GRAY MIXES AND HAVE A GOOD STARTING POINT IN DETERMINING YOUR COLORS.
WHY DO WE SAY TO MEASURE THE COLORS BY "WEIGHT", AND NOT BY VOLUME? NOTE THAT BOTH COLORS IN THE PHOTOS BELOW WEIGH ONE OUNCE. NOTE ALSO THE "VOLUME" OF COLOR IN EACH OF THOSE SINGLE EXAMPLES.
Here is a side-by-side difference between Terra Cotta and Harvest Gold/Goldenrod
MAUVE-----------------------UPDATE: #492 MAROON - 1 oz. (by weight) per 20 lbs. of standard gray Portland or Sand Mix.
CHOCOLATE--------------UPDATE: #338 CHOCOLATE BROWN. 1 oz. (by weight) per 20 lbs. of standard gray Portland or Sand Mix
Here is the difference between Terra Cotta and Harvest Gold/Goldenrod
LIGHT GRAY = 1 oz. ( by weight) WHITE per 20 lbs. cement Portland or Sand Mix
MEDIUM GRAY = Use straight Portland or Sand Mix
DARK GRAY = 1 oz. BLACK (by weight) per 20 lbs. Portland or Sand Mix

The tiles pictured below were colored with 15 grams of color per four pounds of Sand Mix, which will fill one 12"x12"x.5" Tile Mold. Note that colors are not quite as deep as the pavers pictured above due to less color being used in the mix
