Example: Let’s say you are blending a color and you use 5 lbs. of Red and 4 lbs. of Blue. The units can be anything you want to use, pounds, ounces, grams, etc.
In the calculator above, you will enter Red and Blue in the Base Colors column and 5 and 4, respectively, in the Weight column. Clicking the Calculate button will give you ratios of 0.666 and 0.333. This is your formula.
Now, let’s say you want to blend 17 pounds of this color from scratch. Here’s how you would determine the amount of Red and Blue to mix together:
17 lbs. multiplied by 0.666 = 11.322 lbs. of Red
17 lbs. multiplied by 0.333 = 5.661 lbs. of Blue
Theoretically, ratios should add up to 1.000, or percentages to 100.0. However, slight discrepancies are possible due to rounding issues. You may disregard these minute variations.
