Greetings! Can someone help me figure out an equation? Here's the challenge: I need to mix black and white paint to create a grayscale. When you mix black and white, you get gray, and depending on the amount of each, you get a different value of gray (in between white=0 and black=100). I would like to have an equation that would return the remaining variable if I input the value variable and either black or white. I have a table of actual data:
Appreciate any help/ideas. You can email me directly at pmjacobs@sbcglobal.net.
