This extremely simple and easy to use calculator contains the color formulas for 13 popular earth tones, white, grays and black. Simply enter the weight of your cementitious content (cement plus pozzolans), and the calculator tells you exactly how much of each pigment to use, to the milligram.
All of the formulas are based on white cement, including Natural Gray! This makes it possible to have total precision and reproducibility of colors.
The calculator is a Microsoft Excel spreadsheet that is emailed to you upon purchase. Simply download the Excel file to your computer, and start making these popular colors.
