Color and transparency are typically treated independently. Choose a color and set its opacity (or alpha, if you prefer). Simple enough. But, how exactly are color and opacity related?


This app generalizes the calculations for all shades of gray. Provide any 3 of the values requested to calculate the remaining 4th value. Color values must be whole numbers between 0 and 255. Opacity must be between 0% and 100%.
